Try the following macro for creating the new tables. They'll appear after the existing ones.
Code:
Sub Demo()
Dim wdDoc As Document, Tbl As Table, Rng As Range, i As Long, j As Long, k As Long
Application.ScreenUpdating = False
Set wdDoc = ActiveDocument
With wdDoc
For i = .Tables.Count To 1 Step -1
With .Tables(i).Range
j = (.Cells(.Cells.Count).RowIndex - 1) / 2
.Paragraphs.Last.Next.Range.InsertBefore vbCr & vbCr & vbCr & vbCr
Set Rng = .Paragraphs.Last.Next.Next.Range
Rng.Collapse wdCollapseStart
Set Tbl = wdDoc.Tables.Add(Range:=Rng, NumRows:=2, NumColumns:=4, AutoFitBehavior:=False)
With Tbl
.Borders.Enable = True
.Rows.HeightRule = wdRowHeightExactly
.Rows(1).Height = InchesToPoints(0.25)
.Rows(2).Height = InchesToPoints(0.5)
.Cell(2, 1).VerticalAlignment = wdCellAlignVerticalCenter
.Columns.PreferredWidthType = wdPreferredWidthPoints
.Rows(1).Shading.BackgroundPatternColorIndex = wdTurquoise
.Columns(1).Shading.BackgroundPatternColorIndex = wdTurquoise
.Columns(1).Width = InchesToPoints(0.45)
.Columns(2).Width = InchesToPoints(1.5)
.Columns(3).Width = InchesToPoints(2.38)
.Columns(4).Width = InchesToPoints(2.33)
Set Rng = .Range
With Rng
.SetRange Start:=.Cells(6).Range.Start, End:=.Cells(8).Range.End
.Cells.Split NumRows:=2, NumColumns:=1, MergeBeforeSplit:=False
.Rows.HeightRule = wdRowHeightExactly
.Cells.Height = InchesToPoints(0.25)
.SetRange Start:=Tbl.Range.Cells(9).Range.Start, End:=Tbl.Range.End
.Cells.Merge
.SetRange Start:=Tbl.Range.Cells(5).Range.Start, End:=Tbl.Range.End
.Copy
End With
For k = 2 To j
With .Range.Paragraphs.Last.Next.Range
.InsertBefore vbCr
.Paste
End With
Next
End With
End With
Next
End With
Application.ScreenUpdating = True
End Sub
