You can modify the layout of an existing table by adding or deleting rows and columns anywhere in the table.
Add to the Table
Click in the table next to where you want to add a row or column.
On the Table Tools Layout tab, choose what you want to add.
Try This!
Create a table with three columns and three rows. Click in the top-left cell. Drag the mouse to the right to select the first two cells. Click the Table Tools Layout tab, and then click Insert Left. With the new columns selected, click Insert Above. Note that the number of rows and columns that are inserted is based on the number of rows and columns in which cells were selected. Now try deleting rows and columns to revert to the size of the original table.
Tip
To delete the content of a row or column without deleting the row or column itself, select the row or column, and press the Delete key.
Caution
If you want to delete content from a row or column without deleting the row or column itself, make sure your selection doesn’t extend above or below the table. If it does, you’ll delete whatever part of the table is selected, as well as its content.
Delete from the Table
Click in a table cell that’s in the row or column you want to delete.
On the Table Tools Layout tab, click Delete, and choose what you want to delete.
