To insert a new, empty table at any location within your document, follow these steps:
Move the cursor to the document location where you want the table.
Select Table, Insert Table. The Insert Table dialog box appears (see Figure 22.1).
In the Number of Columns and Number of Rows text boxes, click the arrows or enter the number of rows and columns the table should have. (You can adjust these numbers later.)
In the Column Width text box, select the desired width for each column, in inches. Select Auto to have the page width evenly divided among the specified number of columns.
Select OK. A blank table is created with the cursor in the first cell.
