Even after a table is created, you can add additional rows and columns. Whether you add new cells within the current range or adjacent to the table, they will automatically be formatted to match the current table style.
Click anywhere outside the cell or press the Enter key to add the value.
The new row or column is added to the table and the table formatting is applied.
When a formula is entered in a blank column of a table, the formula automatically fills the rest of the column, without using the AutoFill feature. If rows are added to the column, the formula appears in those rows as well.
