Can't Merge Cells in Word after Splitting and deleting

[herrmlm]

Hi, I will try to explain my problem the best I can. I have a table
and the first column's text went with 6 rows (in the 2nd column) so the
first column was merged to show this. I split cells in the first
column to go with the 6 adjacent rows, then I deleted some rows, and
tried to remerge the first column and it won't give me the option to
merge. I can merge some of the cells, but can't merge the ones that
went above the rows I deleted. Any information on how to fix this
problem would be greatly appreciated!

Thanks!
