/* ==========================================================================
   Responsive data table (phones, <= 767px)

   Opt in with class="neba-data-table" on a <table> that has a <thead>.
   Convention: column 1 is a short identifier (rank, year), column 2 is the
   name, column 3 is the key value. Every column after the third is secondary:
   hidden on phones until the row is tapped. Behavior lives in
   js/neba-data-table.js, which labels the secondary cells from the headers.
   Wider screens render the table unchanged.
