I have a table in Word with 3 rows and 20 columns. I am trying to take the 1st row and merge the 1st 8 cells into one to make a "header" over the 2nd, 3rd, and 4th columns. When I execute the merge code below, it merges the columns together, but moves all the other columns to the left. I want to perform the merge much like you do it in Word where you highlight the cells, select merge and the 3 cells become one leaving the same width.
object startRange = oTable.Rows.Cells.Range.Start;
object endRange = currentRow.Cells.Range.End;
Word.Range mergeRange = aDoc.Range(ref startRange, ref endRange);
