Select one instance of the table along with a paragraph above and below that table and then go to the Developer Tab and click on the Repeating Section Content Control button.
You can then use the plus button on the bottom right to add more sections. You can right click to add or remove sections. You can also add a macro to ask for a count and do them all at once.
Code:
Sub RepeatMe()
Dim aCC As ContentControl, iCount As Integer
Set aCC = ActiveDocument.SelectContentControlsByTitle("Repeater")(1)
iCount = InputBox("How many?", , 5)
With aCC.RepeatingSectionItems
If iCount > .Count Then
Do While .Count < iCount
.Item(.Count).InsertItemAfter
Loop
ElseIf .Count > iCount Then
Do While .Count > iCount
.Item(.Count).Delete
Loop
End If
End With
End Sub
