// Reserve space for table sortable controls
// This selector is not perfect as it will not correctly handle cases with
// merged header cells, so ensure it is removed after the JS has run by using
// the :not( .jquery-tablesorter ) selector.
// It will still prevent a visible jump in the majority of simpler cases.
// The second selector in this rule is for after the JS has run.
