Looks are built in tables. Select Show Gridlines from the Table menu to see each cell in the table framed by a grid. You can change the width of an entire column of cells by dragging its border. You can change the width of an individual cell by dragging its border. You can also change cell and column widths by using the commands on the Word Table menu.

You can change the amount of space between the cell grid and the text in the cell. Increasing the amount of space between the text and the cell grid is helpful when you are using borders in your Looks. When the text is too close to the cell border, readability is reduced.
