Table borders are the lines in a table that mark where the rows and columns are. Borders are convenient for entering data in a table. You can see clearly where to enter each data item. But sometimes a table looks better without the borders.
The Hide Borders button acts like a toggle, making it easy for you to hide or display table borders as needed.
Click anywhere in the table.
On the ribbon, click the Table Tools | Layout contextual tab.
In the Format group, click Hide Borders.
If borders are currently displayed, they are hidden. To redisplay them, click in the table and then click the Hide Borders button again.
