VB for Apps - Word Macro Question

I have a table in my Word document (Table1). How do I code my macro to select the first or last row? Thank you.

I found the answer in another forum:

Dim oTable As Table
Dim rngRow As Range
Dim iRow As Integer
Set oTable = ActiveDocument.Tables(1)
iRow = oTable.Rows.Count
Set rngRow = oTable.Rows(iRow).Range
rngRow.Collapse direction:=wdCollapseStart

... Now I just need to figure out how to move to the next cell. Ideas?

The following works better because it does not require the insertion point to be in the table for it to work:

Dim oTable As Table
Dim rngRow As Range
Dim iRow As Integer
Set oTable = ActiveDocument.Tables(1)
iRow = oTable.Rows.Count
Set rngRow = oTable.Rows(iRow).Range
ActiveDocument.Tables(1).Rows(iRow).Select
Selection.InsertRowsBelow

Now, how do I move from cell to cell? I'm still working on this... Any ideas?
