When inserting a table into Excel, you must always select the cells to use for the table data.
To insert a table into Excel, follow these steps:
1. Select the range of cells that you want to include in the table. This range should include the column headers, as they will be used as the headers for the table.
2. Click on the "Insert" tab in the Excel ribbon.
3. Click on the "Table" button in the Tables group.
4. In the Create Table dialog box, make sure that the range of cells you selected is correct. If not, you can click and drag to adjust the range.
5. Check the box for "My table has headers" if your range includes column headers.
6. Click "OK" to create the table.
The selected cells will now be formatted as a table in Excel, with features like filter buttons in the headers and structured reference formulas for easy data analysis.
