Research direction

Start in useWidthColumns.js at parseColWidth and follow its call from useWidthColumns, as shown in the stack trace. Reproduce a virtual table with a column width of null, then ensure this input no longer causes the reported TypeError and verify the table's resulting column-width behavior.
