Hi,
I am no expert, but check out the documentation on the table object. Hope it
helps.
Determines how Microsoft Word resizes a table when the AutoFit feature is
used. Word can resize the table based on the content of the table cells or
the width of the document window. You can also use this method to turn off
AutoFit so that the table size is fixed, regardless of cell contents or
window width.
expression.AutoFitBehavior(Behavior)
expression Required. An expression that returns a Table object.
Behavior Required WdAutoFitBehavior. How Word resizes the specified table
with the AutoFit feature is used.
WdAutoFitBehavior can be one of these WdAutoFitBehavior constants.
wdAutoFitContent
wdAutoFitWindow
wdAutoFitFixed
Remarks
Setting the AutoFit behavior to wdAutoFitContent or wdAutoFitWindow sets the
AllowAutoFit property to True if it's currently False. Likewise, setting the
AutoFit behavior to wdAutoFitFixed sets the AllowAutoFit property to False if
it's currently True.
Example
This example sets the AutoFit behavior for the first table in the active
document to automatically resize based on the width of the document window.
ActiveDocument.Tables(1).AutoFitBehavior _
wdAutoFitWindow
