A simple google search found http://www.secondpersonplural.ca/jqgriddocs/_2h30rdx62.htm

added property forceFit (boolean, default false) When set to true and resizing the width of a column, the adjacent column (to the right) resizes so that the overall grid width is maintained (e.g., reducing the width of column 2 by 30px increases the size of column 3 by 30px). In this case there is no horizontal scrolbar. Note: this option is not compatible with shrinkToFit option - i.e if shrinkToFit is set to false, forceFit is ignored.
