Bearing in mind that there are no 'pages' in a Word document, if your selected range is in a table. then the following is an example of code to move the selection before the table.
Code:
Dim orng As Range
Dim oTable As Table
Set orng = Selection.Range
If orng.Information(wdWithInTable) = True Then
Set oTable = orng.Tables(1)
orng.Start = oTable.Range.Start
orng.Collapse 1
orng.Select
Selection.SplitTable
Set orng = Selection.Range
orng.Text = "The selection is before the table"
Else
orng.Text = "The selection is not in a table"
End If
