Hundreds of thousands of tables need to be set to all sizes. Manual is useless.
Record the way that Word selects tables in bulk
Alt+f8, open the Macro dialog box and create a macro named Selectalltables
Sub selectalltables () DimtempTable As Table Application.ScreenUpdating = False ' Judging if the document is protected IfActiveDocument.ProtectionType = wdAllowOnlyFormFields Then MsgBox "The document is protected and you cannot select multiple tables at this time!" " Exit Sub End If " Delete all editable regions ActiveDocument.DeleteAllEditableRanges wdEditorEveryone ' Add editable Regions For EachtempTable In ActiveDocument.Tables tempTable.Range.Editors.Add wdEditorEveryone Next ' Select all editable Regions ActiveDocument.SelectAllEditableRanges wdEditorEveryone ' Delete all editable regions    ACTIVEDOCUMENT.DELETEALLEDITABLERANGES WDEDITOREVERYONE  &NBSp; application.screenupdating = true end sub
Copy, run. Wait for the selected end to switch to the document to see the full selection effect.
--over!
