Cells Fundamentals

 Introduction
 In Lesson 3, we saw that a list could be described as a series of categories called columns. In Lesson 4, we saw that a list organized the values of columns in horizontals sections called rows.
 As a list is made of columns and rows, they intersect. The intersection of a column and a row creates a small box called a cell:

In Lesson 3, we saw that, when Microsoft Excel starts, it creates 16,384 columns. In Lesson 4, we saw that when Microsoft Excel starts, it creates 1,048,576 rows. As a result, when you open Microsoft Excel, you have a total of 16,384 * 1,048,576 = 17,179,869,184 cells available. You can use just a few of them, as will usually be the case, or you can use as many as you want but they are always available.

Among the various ways you can use a cell, we will see in various sections that you can click it or use the keyboard to get to a cell. You can also right-click a cell. When you do, a multi-part menu would appear:

Notice that the context-sensitive menu is divided in two sections; a toolbar and a menu window. Throughout our lessons, we will see what the buttons and the menu items represent.

 The Location of a cell

Whatever you are doing on a cell, it is always important to know what cell you are working on. The minimum piece of information you need about a cell is to know which one you are using at a particular time. To make this recognition a little easier, each cell has an address also called a location. This address or location also serves as the cell's primary name.

To know the location of a cell, you refer to its column and its row. The combination of the column's name and the row's label provides the address or name of a cell. When you click a cell, its column header becomes highlighted in orange. In the same way, the row header of a selected cell is highlighted in orange. To know the name of a cell, you can refer to the Name Box, which is located at the intersection of columns and rows' headers:

 Selecting Cells

 Introduction

Before doing anything on a cell or a group of cells, you must first select it. Selecting cells is almost equivalent to highlighting a word in a text document. Various means are available to select a cell or a group of cells. You can use the mouse only, the keyboard only, or a combination of the mouse and keyboard.

 Selecting a Cell

At almost any time, at least one particular cell is selected. The selected cell has thicker borders than the other cells. That cell is referred to as the active cell. This is important because you always need to know where the changes you are making are being applied. This means that, whatever you type or format will apply to that particular cell. Sometimes you will want to work on many cells simultaneously. Therefore, you first have to select the intended cells before proceeding.

As mentioned already, you can select a cell using the mouse, the keyboard, or a combination:

• To select a cell using the mouse, just click it. To select another cell, click the new one
• To select a cell using the keyboard, since you may have to move focus from one active cell to another, press the arrow keys until the desired cell is selected
• To select a cell based on its name and using the mouse and keyboard, click in the Name Box, and type the name or address of the cell
• To select the first cell of the document using the keyboard only, press Ctrl + Home
 Practical Learning: Selecting Cells
1. To select one cell at a time, click cell B6
2. Click cell C4
3. Click cell E8
4. Press the down arrow key
5. Press the right arrow key three times
6. Press Ctrl + Home
 Selecting Cells

Instead of only one cell, you may want to perform a common operation on many cells, which means you must select them first. You can use the mouse, the keyboard, or a combination. You can select cells based on columns or based on rows. You can select cells in a particular region; that is, adjacent cells, or you can select non-adjacent cells:

• To select all cells of a column:

• In the Name box, type the name of a cell of that column and press Enter. Then press Ctrl and the Space bar
• To select all cells of a series of columns, select those columns as seen in Lesson 2 and notice that all cells in the selected columns are selected
• To select all cells of a row:
• Click the row header as seen in Lesson 3
• In the Name box, type the name of a cell of that row and press Enter. Then press Shift and the Space bar
• To select all cells of a series of rows, select those rows as seen in Lesson 3 and notice that all cells on the right side of the selected rows are highlighted
• To select cells in the same region using the mouse only, click and hold your mouse on one cell, then drag down or up, left or right, to the last cell in the range
• To select cells in the same region using the keyboard only, press the arrow keys a few times until the cell that will be at one corner is selected. Press and hold Shift. Press the arrow keys left, right, up, or down. If you press the right arrow key, the currently highlighted cell and the cell to its right would be selected. If you press the down arrow key, the current cell and the cell under it will be highlighted. You can also press the left or up arrow key. You can press the arrow keys many times in the direction of your choice. Once you have achieved the selection you want, release the Shift key
• To select non-adjacent cells, click one of the cells. Press and hold Ctrl. Click each of the desired cells. Once the selection is complete, release Ctrl
• To select all cells on a worksheet, you can press Ctrl + A. Alternatively, you can click the button at the intersection of the row header and row headers

 The Size of a Cell

 Introduction

A cell uses a combination of the width of its parent column and the height of its parent role to determine its size. This means that the width of a cell is the width of its column and its height is that of its row. Therefore, to change or specify the size of a cell, you use the technique of setting the width of columns or the height of cells as we saw in Lessons 3 and 4.

 Controlling the Widths of Cells

In future lessons, we will see how to enter values in cells. We will find out that it is not unusual that the content of a cell goes beyond its normal size. To show the hidden content of a cell, you can resize it.

As seen in Lesson 2:

• To control the width of all cells of a column, position the mouse on the separating line between two column headers. Drag left or right until you get the desire width. Then release the mouse.
• To change the widths of cells of a group of columns, first select the columns, whether in a range or randomly. Position the mouse on the column header border of one of the selected columns. Click and drag left or right in the direction of your choice until you get the desired with. Then release the mouse.
• If a cell under a column header displays the width you want, click the box that has the desired width. Then:
• Double-click the separating line between the column header
• On the Ribbon, click Home. In the Cells section, click Format and click AutoFit Column Width
• If many columns have some cells width a desired width, select those cells as we saw earlier. Then:
• Double-click the separating line on one side of the column headers
• On the Ribbon, click Home. In the Cells section, click Format and click AutoFit Column Width
• To precisely set the width of cells under a column:
• Right-click the column header and click Column Width...
• Click a column header or any of its cells. On the Ribbon, click Home. In the Cells section, click Format and click Column Width...
• To specify the same width for many columns:
• Select a range of columns. Right-click either one of the column headers or inside the selection and click Column Width...
• Randomly select a group of (non-adjacent) columns. Right-click one of the column headers and click Column Width...
• Select the columns, whether in a range or randomly (non-adjacent). On the Ribbon, click Home. In the Cells section, click Format and click Column Width...
Any of these actions would open the Column Width dialog box. From there, accept or enter the desired value and click OK

To undo any of these actions:

• Press Ctrl + Z
 Practical Learning: Setting the Widths of Cells
1. Click Cell D4 to select it
2. On the Ribbon, click Home if necessary.
In the Cells section, click Format and click AutoFit Column Width
3. Select Cells E4:I4
4. In the Cells section of the Ribbon, click Format and click Column Width...
5. Type 10 and click OK
6. Press Ctrl + Home
 Controlling the Heights of Cells

In Lesson 3, we saw different techniques of setting or controlling the heights of rows. Actually, these apply to cells on the right side of the rows. As a reminder:

• To change the height of the cells of a row, click the lower border of a row header. Drag up or down until you get the desired height. Then release the mouse
• To change the height of cells on the right sides of a group of rows, first select the rows. Position the mouse on the bottom border of one of the selected rows. Click and drag up or down in the direction of your choice until you get the desired height. Then release the mouse.
• If the cells on the right side of a row header are too short or too tall, to change their height:
• Double-click the bottom border of the row header
• Click the row header. On the Ribbon, click Home. In the Cells section, click Format and click AutoFit Row Height
• To precisely specify the height of cells of a row:
• Right-click the row header and click Row Height...
• Click a row header or any box on its right side. Then, on the Ribbon, click Home. In the Cells section, click Format and click Row Height...
• To precisely set the same height for cells of many rows:
• Select a range of rows. Right-click either one of the row headers or inside the selection and click Row Height...
• Randomly select a group of (non-adjacent) rows. Right-click one of the row headers and click Row Height...
• Select the rows. On the Ribbon, click Home. In the Cells section, click Format and click Row Height...
This would call the Row Height dialog box where you can type the desired value and click OK or press Enter

To undo any of these actions:

• Press Ctrl + Z

 Creating Cells Vertically

As mentioned already, when Microsoft Excel starts, it creates billions of cells for you. As we will see in the next lessons, you can then use the cells to enter the values you want in your spreadsheet. As a list displays its values, you may want to insert a value between two existing cells.

In Lesson 2, we saw that you could insert a new column to get new cells on the left side of a series of existing cells. Instead of using the column to perform this operation, you can do it from inside the cells.

• Right-click a cell that belongs to the column that will follow the new column and click Insert... This would open the Insert dialog box. To insert a new column, click the Entire Column radio button before clicking OK:

• Click a cell. On the Ribbon, click Home. In the Cells section, click the arrow button under Insert and click Insert Sheet Columns
• Click a cell. On the Ribbon, click Home. In the Cells section, click the arrow under Insert and click Insert Cells... This would open the Insert dialog box. To insert a new column, click the Entire Column radio button and click OK

When you perform any of these operations, a new column would be created on the left side of the column whose cell was clicked or right-clicked:

To add more than one column, first select the cells, either in a range:

Or at random:

Then:

• Right-click one of the selected cells and click Insert... In the Insert dialog box, click the Entire Column radio button and click OK
• Click a cell. On the Ribbon, click Home. In the Cells section, click the arrow under Insert and click Insert Sheet Columns
• Click a cell. On the Ribbon, click Home. In the Cells section, click the arrow under Insert and click Insert Cells... This would open the Insert dialog box. To insert a new column, click the Entire Column radio button and click OK

When you perform one of these actions, if the cells were selected in a range, the same number of columns would be created on the left side of the range that was selected. If the selected cells where not adjacent, new columns would be created on the left side of the column of each cell that was selected or on the left side of each group of cells that were selected.

The techniques of inserting columns that we saw in Lesson 2 and above are used to add a complete column. Sometimes, you will want to create, add, or insert a new cell between two existing cells. To perform this operation vertically, you would ask Microsoft Excel to consider a cell, move all cells under it by one step down. Once this is done, you would be presented with a new empty cell where the other was.

To insert a cell vertically between two cells:

• Right-click the cell that will be pushed down along with the cells under it, and click Insert...

• Click the cell that will be pushed down along with its bottom neighbors. On the ribbon, click Home. In the Cells section, click the arrow button under Insert, and click Insert Cells...

Any of these actions would call the Insert dialog box. From it, to insert a cell and push the other cells down, click the Shift Cells Down radio button:

When you click OK, each cell would be pushed down up to the cell that must be created:

In the same way, you can first select cells in a column, either in a range or randomly, and insert new cells.

To undo any of these actions:

• Press Ctrl + Z
 Creating Cells Horizontally

In Lesson 3, we saw that you could add a new row to get a new series of cells aligned horizontally. Those operations can also be performed from cells.

• Right-click a cell that belongs to the row that will be below the new row and click Insert... This would open the Insert dialog box. To insert a new row, click the Entire Row radio button and click OK
• Click a cell. On the Ribbon, click Home. In the Cells section, click the arrow button under Insert and click Insert Sheet Sheet Rows
• Click a cell. On the Ribbon, click Home. In the Cells section, click the arrow under Insert and click Insert Cells... This would open the Insert dialog box. To insert a new column, click the Entire Column radio button and click OK

Any of these actions would add a new row above the cell that was selected.

To add more than one column, first select the cells, either at random or in a range

Then:

• Right-click one of the selected cells and click Insert... In the Insert dialog box, click the Entire Row radio button and click OK
• Click a cell. On the Ribbon, click Home. In the Cells section, click the arrow under Insert and click Insert Sheet Rows
• Click a cell. On the Ribbon, click Home. In the Cells section, click the arrow under Insert and click Insert Cells... This would open the Insert dialog box. To insert a new column, click the Entire Row radio button and click OK

If the cells were selected in a range, the same number of rows would be created above the cells. Imagine the selected cells where not adjacent:

If you insert the rows, a new row would be inserted above each selected row:

Any of these techniques adds a complete row to the list. Sometimes, you will only want to add a new cell. You can ask Microsoft Excel to push some cell to the right and create room for one or more new cells.

To insert a cell horizontally between two cells:

• Right-click the cell that will be pushed to the right along with the cells on its right, and click Insert...
• Click the cell that will be pushed to the right along with its right neighbors. On the ribbon, click Home. In the Cells section, click the arrow button under Insert, and click Insert Cells...

Any of these actions would call the Insert dialog box. From it, to insert a cell and push the others to the right, click the Shift Cells Right radio button.

To undo any of these actions:

• Press Ctrl + Z
 Removing Cells

 Introduction

Besides adding cells, a list maintenance also consists of deleting or moving cells. In Lesson 2, we saw how to delete one or more columns. The problem is that, when you delete a column, all of its cells a lost. In the same way, if you delete a row, all of its cells are lost also. Sometimes you want to remove only one or more cells but keep the other cells of the same column or the same row. Fortunately, Microsoft Excel supports various techniques of removing cells from a list.

Instead of deleting a whole column, you can delete just one cell or more cells. Because a cell is surrounded by other cells, you must indicate what would happen to the other cells or how they would adjust to he new empty spot.

 Deleting a Cell

Before deleting a cell, you first make it active. Then you specify if, by removing it, the cells on on its right would be moved to the left to close the left empty space. The alternative it to draw the cells from under it up. When the cell has been removed, and the cells from the right side have been move left, Microsoft Excel adds a new cell from the last column. If the cells have moved up, Microsoft Excel creates a cell in the last position of that column.

To delete a cell:

• Right-click the cell and click Delete...

• Click the cell. On the Ribbon, click Home. In the Cells section, click Delete and click Delete Cells...

This would display the Delete dialog box. To

To delete more than one row, first select the rows, whether in a range or randomly. Then:

• Right-click one of the rows (whether one of the row headers or a box on the right side of one of the selected rows) and click Delete
• (After selecting the rows,) On the Ribbon, click Home. In the Cells section, click Delete and click Delete Sheet Rows
