public function AutofitCol( 
   col1 : int,
   col2 : int,
   ignoreStrings : boolean,
   adjustment : double
);

Parameters

col1

First column to Autofit.

col2

Last column to Autofit.

ignoreStrings

When true, strings will not be considered for the autofit. Only numbers will.

adjustment

You will normally want to set this parameter to 1, which means that autofit will be made with standard measurements. If you set it to for example 1.1, then columns will be adjusted to 110% percent of what their calculated width was. Use this parameter to fine-tune autofiting, if for example columns are too small when opening the file in Excel.
