In Excel, you have another alignment option available to you: Merge and Center.
When you merge a cell, you are selecting more than one cell and are creating one large cell. You can center the contents of a cell across the new merged cell.
Merge and Center is helpful when creating worksheet titles.
Excel only centers the text in the top-left cell of the selection, so if the title is in more than one row, you will need to merge and center each title row separately.
