To add a table in a Microsoft Word file, you should go to the Insert tab on the Ribbon. Then, click on Table. You have several options:

• For a quick basic table, hover over the grid to highlight the number of rows and columns you want, then click to insert it.
• For a larger or customized table, choose Insert Table from the dropdown, then enter the number of rows and columns in the dialog box and click OK.
• You can also select Draw Table to manually draw the table with custom rows and columns.

After inserting, you can format and edit the table using the Table Design and Table Layout tabs that appear in the Ribbon when the table is selected
