lock part list column width

[classicac]

Hello all,

 

I am trying setup a default part list for my company in Inventor, where I am stuck at is I wish to lock the width of the columns so on all our drawings the part list is the same width, I have assigned each column its own width and when I bring it in to the drawing it's the correct size but I am able to drag the edges, and change its size, I want to lock it so if you try you cant.

am I missing something obvious in the menus? Or is this a limitation with inventor.

I am using the latest version of Inventor 2013

 

Cheers
