What action should you take to insert a new row in a table?

To insert a new row in a table, pressing the Tab key is the correct action. In most word processing software, including Microsoft Word, the Tab key is designed to navigate through table cells. When you are in the last cell of a row and you press Tab, a new row is automatically created below the existing row. This functionality allows users to efficiently expand their tables without needing to access the menu or toolbar to insert rows manually.

While other keys listed have distinct functions, they do not achieve the same result. For instance, pressing Enter typically creates a new line within the same cell rather than adding a new row to the table. Therefore, using the Tab key is the most effective method for adding rows smoothly while working within a table.
