Sir, your AutoFitColumn() is a terrific feature. Very useful.
It appears to fit the columns very tightly - a little too tightly
Can you add an optional parameter in the function call to specify additional padding width that is added to each column, so they are a bit wider then that AutoFit algorithm calculates
this.grid.autoFitColumns('15px'); //adds 15px to the width of every auto calculated column to make them wider
this.grid.autoFitColumns('-12px'); //subtracts 12px to the width of every auto calculated column, to make them even tighter
