每页打印标题

Question

我在主题Print subtotals on each page with HTML/CSS/JS maybe XSLT?中找到了一个代码（如下所示）。 我想在每个页面上添加标题表。 你能让我知道如何正确地做吗？ 先感谢您。

<script>
  function printSubtotals(table, columns) {
    var
      tbody = table.tBodies[0],
      row = tbody.rows[0];
    if(!row)
      return;
    var cellCount = row.cells.length;
    if(!cellCount)
      return;
    var
      subtotals = [],
      rows = table.rows,
      thead = table.tHead,
      caption = table.querySelector('caption'),
      colgroup = table.querySelector('colgroup'),
      emptyTable = table.cloneNode(false),
      emptyRow = row.cloneNode(true),
      printDiv = document.createElement('div'),
      overlap = document.createElement('div'),
      subtotalCount = columns.length,
      rowCount = rows.length - 1,
      cells, subtotalCells, i, r;
    if(colgroup && colgroup.parentNode === table)
      emptyTable.appendChild(colgroup.cloneNode(true));
    emptyTable.appendChild(tbody.cloneNode(false));
    printDiv.className = /MSIE /.test(navigator.userAgent) ? 'print fixIE' : 'print';
    overlap.className = 'overlap';
    for(i = subtotalCount; i--; subtotals.push(0)); 
    for(i = cellCount; i--; emptyRow.cells[i].innerHTML = '');
    for(r = row.rowIndex; r < rowCount; r++) {
      printDiv.appendChild(overlap.cloneNode(true));
      tbody = printDiv.appendChild(emptyTable.cloneNode(true)).tBodies[0];
      cells = tbody.appendChild(rows[r].cloneNode(true)).cells;
      subtotalCells = tbody.appendChild(emptyRow.cloneNode(true)).cells;
      for(i = subtotalCount; i--;) {
        subtotals[i] += parseFloat(cells[columns[i]].innerHTML);
        subtotalCells[columns[i]].innerHTML = '<b>Total: ' + subtotals[i] + '</b>';
      }
    }
    printDiv.removeChild(printDiv.children[0]);
    tbody = printDiv.children[0].tBodies[0];
    if(caption && caption.parentNode === table)
      tbody.parentNode.insertBefore(caption.cloneNode(true), tbody);
    if(thead)
      tbody.parentNode.insertBefore(thead.cloneNode(true), tbody);
       table.parentNode.insertBefore(printDiv, table);
  }
  printSubtotals(document.querySelector('.data'), [0,1]);
</script>
