Both the macro worked just fine. Thank you very much.
What I wanted is this. Is It right approach?
Code:
With Tbl.Cell(i, 3).Range
.End = .End - 1
.Collapse wdCollapseEnd
.Text = vbCr & "Abstract: "
.Font.Bold = True
End With
With Tbl.Cell(i, 3).Range
.End = .End - 1
.Collapse wdCollapseEnd
.Text = StrTxt
.Font.Bold = False
End With
