This Javascript (jQuery) will:
find Name and replace it with 'DGN Link'
find PDF Link, Drawing # and DGN Link ('Name' really) and give a width of 100px;
after jQuery is complete it will set the hidden webpart to display:block (keeps user from seeing the magic happen).
Made PDF Link and DGN Link (name) header columns 100px wide. Changes Name column to read 'DGN Link'.
