ALT+F8,打开宏对话框，创建名为SelectAllTables的宏。代码如下：
Sub SelectAllTables()
Dim tempTable As Table
Application.ScreenUpdating = False
'判断文档是否被保护
If ActiveDocument.ProtectionType = wdAllowOnlyFormFields Then
MsgBox "文档已保护，此时不能选中多个表格！"
Exit Sub
End If
'删除所有可编辑的区域
ActiveDocument.DeleteAllEditableRanges wdEditorEveryone
'添加可编辑区域
For Each tempTable In ActiveDocument.Tables
tempTable.Range.Editors.Add wdEditorEveryone
Next
'选中所有可编辑区域
ActiveDocument.SelectAllEditableRanges wdEditorEveryone
'删除所有可编辑的区域
ActiveDocument.DeleteAllEditableRanges wdEditorEveryone
Application.ScreenUpdating = True
End Sub
保存完成后选择加载该宏即可。
