Page Break Is Not Working with the Tbody Issue

Bullet proof solution for page break on table row ( tr ) for printing

It is not nice but you could try to go with separat tables for each row. By using the following syntax you can make sure the columns are rendered in the same widths.

<style>
    table {
        page-break-inside: avoid;
    }
</style>

<table>
    <colgroup>
        <col width="25%" />
        <col width="50%" />
        <col width="25%" />
    </colgroup>
    <tr>
        <td>Narrow column</td>
        <td>Wide column</td>
        <td>Narrow column</td>
    </tr>
</table>
<!-- can break -->
<table>
    <colgroup>
        <col width="25%" />
        <col width="50%" />
        <col width="25%" />
    </colgroup>
    <tr>
        <td>Narrow column</td>
        <td>Wide column</td>
        <td>Narrow column</td>
    </tr>
</table>

Can't page break to work without messing up the table formatting

I figure out an even more hard-coding method (so call perfectly solve your problem). I must said it is not elegant.

My method's main idea is changing tbody to display:block (as usual), but adding the .pagebreak to target tbody as well.

However, this method unattach tbody from the table and thus no longer align with thead. That's why I add a tr for printing thead, and remove the origin thead when print.

Added printing th, don't show in normal view

//Thead part, add a printing thead only shown in Print
//As originaly thead will has alloction problem
{ i % 2 === 1 ?
  <tr className='printing-thead'>
    <td colspan="3">Results</td>
    <td>1</td>
    <td>2</td>
    <td>3</td>
  </tr> : null
}
....
...
//Corrected Page break
</tbody>
<tbody class="pagebreak">
    <tr>
        <td colspan="7"></td>
    </tr>
</tbody>
<tbody>
...

  tr.printing-thead {
    display: none;

@media print {
  thead {
    display: none;

  tbody {
    display: block;
    tr.printing-thead {
      display: contents;
      font-weight: bold;
      text-align: center;
    }

  .pagebreak {
    height: 0px;
    break-before: always !important;
    page-break-before: always !important;
    page-break-inside: avoid !important;

Mutli-row table header wrong page break

It's ok. I created a function that manually adds rows to the table while the table's height is less than the page's height. When the table's height goes beyond page's height, I remove the last inserted row, create a new table with the same header and add the remaining rows to this table.
