1. Merge cells button: This option merges the selected cells into one cell, but it does not automatically center the text within the merged cell.

2. Merge & center button: This option merges the selected cells into one cell and also centers the text within the merged cell. Additionally, it combines the functionality of the Merge cells button and the Align text center button.
