Word Table + Merge Cells + vb.net

I have created a word document and a table within that document.  the table is 2 rows by 6 columns. I need to merge cells 1,2 to 1,6 (so the cell will expand from cells 1,2 to 1,3 to 1,4 to 1,5 and finally to 1,6).  There is a function that looks like this:

oTable.Cell(1, 2).Merge(oTable.Cell(1, 6))

but this will delete cells 1,3 1,4 1,5 and 1,6 so instead of the table being 2,6 the table is 1,2 on the first row and 1,6 on the second row.

I want the table to look like this:

Case Caption |  Defendents                             Vs.                                Plantiffs (this is one string--don't want to break it up)
Client            |  Client's Name                    | File Num          | File Number                 | Case Num         |Case Number



Notice the two cells on row 1 and the 6 cells on row 2.
