When working with tables in Excel, you can resize them by using the Resize Table option in the Table Design tab or by simply inserting a column.

Resize Table by Adding a Column in Table Design

Say you have the sales data table with columns for SKU, Product, Month, and Sales Amount.

If you want to add Price and Total Sales to the table, you’ll need to add two columns to the right.

1. First, select the table by clicking on any cell in it. After that, in the Ribbon, go to the Table Design tab, and in the Properties group, click on Resize Table.

2. In the pop-up screen, change the range for the table and press OK.

Since you want to add two more columns to the right, expand the range for Columns F and G, and the new range is B2:G16. As you can see, when you enter a new range, the dashed line will highlight the table size.

As a result, the table got two new columns (F and G) named Column1 and Column2.
