Let's say you have a list of company transactions. Each transaction includes a department number, a title, and other information (amount, date, time, sales rep, etc.). As you get more and more of these items in your list, you may want a way to automatically add "dividing lines" based on the department number. For instance, when the department number changes, you may want to include a line between the two departments.
To add this type of formatting to your list, start by sorting your data table by department. Then follow these steps:
Figure 1. The Conditional Formatting dialog box.
Figure 2. The Borders tab of the Format Cells dialog box.
That's it; you should now see a line that appears across the entire width of your data every time the department changes.
