Format as Table

The feature that allows you to be automatically added to new columns and rows is "Format as Table."

The feature that allows you to be automatically added to new columns and rows is called "Format as Table". To enable this feature, you can follow these steps:

1. Select the range of cells that you want to format as a table.

2. Go to the "Home" tab in the Excel ribbon.

3. In the "Styles" group, click on the "Format as Table" button.

4. Choose a table style from the gallery that appears, or you can create your own custom table style.

5. In the dialog box that opens, ensure that the "My table has headers" option is checked if your table has column headers.

6. Click on the "OK" button.

Once you've applied the "Format as Table" feature, any new columns or rows that you add to the table will automatically inherit the formatting of the table, including any formulas or formatting rules applied to the existing data. This makes it easier to maintain consistency in your table as it grows or changes.
