https://www.primefaces.org/primeng/v6.1.7/#/table I have added three css properties in order to make thead repeat for primeng table

.ui-table .ui-table-thead {
  page-break-inside: avoid;
  page-break-before : always;
  page-break-after : always;
  // thead th { position: sticky; margin-top:0.3em; top: 0; }
}

html to pdf Output

But the problem in above output is, that bottom line appears before second page and first th background color of thead is getting white, because I'm using row span on that. is there any solution to ignore the page break specifically before that row start
