/* Multi-column table layout, same look as the section cards in section-items.css:
   gold top bar on the header, rounded top corners, light row dividers, hover highlight.
   Works for any number of columns; the columns are whatever the table defines.

       <table class="column-table">
         <thead><tr><th>Project #</th><th>Title</th><th class="col-num">Hours</th></tr></thead>
         <tbody><tr><td>1234</td><td>Library</td><td class="col-num">8</td></tr></tbody>
       </table>

   Modifiers (add to the table):
       column-table-striped   alternate row shading
       column-table-sticky    header stays visible while scrolling; set --column-table-sticky-top
                              to the height of any fixed navbar, e.g. style="--column-table-sticky-top: 90px"
       column-table-fixed     equal-width columns (table-layout: fixed); size one with a width on its th
   Cell helpers: col-num (right aligned numbers), col-center, col-nowrap.

   Wrap the table in <div class="column-table-wrap"> to scroll horizontally on small screens. */
