Steps to Reproduce

1. run the attached file

Current Result

no checkmarks in the first column because the 1st column is invisible

Expected Result

checkmarks are visible

Debug Information

• A listbox always renders the checkmarks at the 1st column no matter it's visible or not. If listbox can render checkmarks in a separate inner column, independent of the 1st column generated from its model, then a column's visibility won't affect the visibility of checkmarks.

Workaround

1. reserve empty first column for checkmarks, render data object starting from the 2nd column
