/**
 * Demonstration of how to customize rendering based on whether

 * the "Passed" column, is given an extended version of TablePrintDemo1's
 * PassedColumnRenderer, which uses clearer black and white versions
 * of the check mark and x mark icons when printing, as determined by
 * calling isPaintingForPrint on the table.
 * <p>
