Left cell? Your question (and code) didn't mention tables. You would need to supply a sample document so that we can see what you are working with.
The page number is simpler
Code:
Do While .Execute
oRng.MoveEndUntil Chr(13)
oRng.End = oRng.End + 1
oRng.MoveEndUntil Chr(13)
Set oEnd = oTarget.Range
oEnd.Collapse 0
oEnd.FormattedText = oRng.FormattedText
oEnd.Collapse 0
oEnd.Text = Chr(32) & "Page " & oRng.Information(wdActiveEndPageNumber)
oEnd.Collapse 0
oEnd.InsertParagraphAfter
oRng.Collapse 0
Loop
