There are quite a few options in this menu.

The key is to choose the line style and line color before choosing the presets.

Let’s take a look.

The border menu is on the home tab of the ribbon, inside the font group.

It contains a long list of border presets.

To use these presets, set the line style and the line color first.

We aren’t drawing borders in this case, so we’ll need to turn that off.

Now we have the standard cursor again and can apply border presets.

The Bottom Border preset adds a border to the bottom of the selection.

The Top Border, Left Border, and Right Border presets work the same way.

The No Border command clears existing borders.

It has no effect if there aren’t any borders in use.

Bottom Double Border and Thick Bottom Border presets also ignore the current line style setting.

Both presets use their own configs for line style.

This is also true of the three presets that apply a top and bottom border.

Each preset respects the current line color setting and uses its own setting for line style.
