Splitting a particluar column into multiple rows

[MCS]

Hi.
I'm brand new to VBA, but have coded in VB before.
In Microsoft Word, starting with a table of 33 rows and 3 columns, I want to split each of the initial 33 rows (of column 3 only) into 10 rows each.
I thought this would be pretty easy, but the code (below) doesn't work. It actually works for the first 2 (of the original) rows, but then the count somehow gets messed up and the third original row doesn't work. I'm not sure why (the count will continue to increase as I am adding 10 rows at a time). As well, the routine ends with no error messages and the job is not complete (except for the first two original rows).

The code I'm using:

Sub SplitColumnIntoRows()
' In Microsoft Word, split each of the initial 33 rows (of column 3 only) into 10 rows each.
Dim tbl As Table
    Dim row As Integer
    Dim rowCount As Integer
    Dim col As Integer
' Set the table reference to my specific table
    Set tbl = ActiveDocument.Tables(1)
' Loop through the appropriate cell in the table (column 3 only)
    col = 3
rowCount = tbl.Columns(col).Cells.Count
For row = 1 To rowCount Step 10
tbl.cell(row, col).Select
' Split cell into desired number of rows
        Selection.Cells.Split NumRows:=10, NumColumns:=1
        rowCount = tbl.Columns(col).Cells.Count
    Next
End Sub

Any illumination would be helpful.
Thank you in advance.
