Hi, thank u for your message， I am sorry to tell you that the Merge Same Cells and Unmerge Cell utilities cannot apply in table, you can right click at the table, then click Table > Convert to range in the context menu to convert the table to range cells first, then apply the Merge Same Cells or Unmerge Cell utilties. Or you can copy the table and paste as value, then apply the utilities. Wish it is helpful.
