/**
 * Tema compartido para tablas DataTables (index de usuarios, videos, etc.)
 *
 * Uso en cualquier index:
 * 1. Este archivo se carga en el layout default; no hace falta incluirlo de nuevo.
 * 2. En tu vista, envuelve la tabla en:
 *    <div class="panel datatable-panel px-0 pb-0"> ... <div class="datatable-wrapper px-4 sm:px-6"> <table id="tuId"> ...
 * 3. Si tienes filtros (ej. usuarios), pon la sección de filtros en un div con class "datatable-filters".
 * 4. Incluye los CSS de DataTables en la vista: jquery.dataTables.min.css y buttons.dataTables.min.css.
 * 5. Inicializa DataTables con dom que use las clases dt-top-row y dt-bottom-row para el mismo layout.
 * Ver app/views/users/index.html.erb y app/views/videos/index.html.erb como referencia.
