Sure, I can help you with that! When you apply a Table Format to a range of cells in Excel, it can sometimes restrict certain formatting options, such as merging cells. However, there is a workaround to merge cells in a table format. Here's how:

1. Select the cells that you want to merge.
2. Right-click on the selected cells and choose "Format Cells".
3. In the "Alignment" tab, check the box that says "Merge cells".
4. Click "OK" to apply the changes.

Alternatively, you can use the "Merge & Center" button in the "Alignment" section of the Home tab. However, this may not work if the cells are part of a table format.
