There is no documented method of aligning decimal numbers when working in tables that I know of. However, you can if you like, add a decimal tab stop in a cell and then click CTRL + Tab to align the number to the tab stop. There is, though, an even easier solution.
Follow the steps below to learn how:
- Select the cell or cells whose content you would like aligned.
- Click on the tab stop marker at the left edge of your Ruler and stop when you see the symbol for a decimal tab.
- Click on your Ruler above the selected cells at the location where you want your numbers aligned.
Now the numbers in that cell will be aligned as per the tab stop.
There is a caveat though, which is this is the only tab option (decimal) that will work this way.
