Chapter 3 Using Tables 65
Using a Checkbox and Other Control Formats
You can add a checkbox, slider, stepper, or pop-up menu to a cell:
 A checkbox is for cells whose value indicates one of two states, such as on or off, or
yes or no.
 A slider is useful for quickly making large changes to numbers so you can see the
effects of the changes on other cells in the table or on a chart.
 A stepper lets you increase or decrease numbers in specific increments.
 A pop-up menu lets you predefine the values a cell can contain.
When a cell is formatted to use a checkbox or pop-up menu, you can add or change a
cell’s content only by using the control. Cells that use a slider or stepper let you type a
value into the cell or use the control; when you click off the cell, the value changes
depending on the settings you make when you define the slider and stepper.
Here are ways to add controls to cells:
m To add a checkbox, select the cell or cells.
Click the Checkbox button in the Format Bar. Unchecked checkboxes are added to
