Try something like:
Code:
Sub Demo()
Application.ScreenUpdating = False
Dim Tbl As Table, FndList, RepList, i As Long
FndList = Array("Replace", "Do")
RepList = Array("Replaced", "Done")
With ActiveDocument
For Each Tbl In .Tables
With Tbl.Range.Find
.ClearFormatting
.Replacement.ClearFormatting
.MatchWholeWord = True
.Replacement.Text = "^&"
.Wrap = wdFindStop
For i = 0 To UBound(FndList)
.Text = FndList(i)
.Replacement.Text = RepList(i)
.Execute Replace:=wdReplaceAll
Next
End With
Next
End With
Application.ScreenUpdating = True
End Sub
The above code only looks in tables in the body of the document. To add more Find/Replace expressions, simply edit the two arrays - FndList & RepList.
