Apply cell borders

Borders help visually group similar cells and draw attention to important details.

Here's how you can apply them to your data:

Select the range of cells that you wish to apply borders to.
Click under the Home tab.
From the Borders dialog, you can select a border type, line type and line color.

If you select a range like C1:D6, and apply a left border, the border will only appear along the left edge of cells C1:C6.
