xslt - Split large table into several smaller tables

Question

I have a problem where a table has 100s of rows. It causes an issue and needs to be split into several smaller tables with fewer rows each.

My html is valid xml as well.

How can I split the table every x rows into a new table?

And, how can I copy the table style, and first row (header) into each subsequent table.

So something like this

<table class="..." style="...">
   <tr>
       <td>head 1</td>
       <td>head 2</td>
   </tr>

   <tr>
       <td>col1</td>
       <td>col2</td>
   </tr>

   <tr>
       <td>col1</td>
       <td>col2</td>
   </tr>

   <tr>
       <td>col1</td>
       <td>col2</td>
   </tr>

   <tr>
       <td>col1</td>
       <td>col2</td>
   </tr>

   <tr>
       <td>col1</td>
       <td>col2</td>
   </tr>

   <tr>
       <td>col1</td>
       <td>col2</td>
   </tr>
<table>

Becomes

<table class="..." style="...">
   <tr>
       <td>head 1</td>
       <td>head 2</td>
   </tr>

   <tr>
       <td>col1</td>
       <td>col2</td>
   </tr>

   <tr>
       <td>col1</td>
       <td>col2</td>
   </tr>
</table>

<table class="..." style="...">
   <tr>
       <td>head 1</td>
       <td>head 2</td>
   </tr>

   <tr>
       <td>col1</td>
       <td>col2</td>
   </tr>

   <tr>
       <td>col1</td>
       <td>col2</td>
   </tr>
</table>

<table class="..." style="...">
   <tr>
       <td>head 1</td>
       <td>head 2</td>
   </tr>

   <tr>
       <td>col1</td>
       <td>col2</td>
   </tr>

</table>

<table class="..." style="...">
   <tr>
       <td>head 1</td>
       <td>head 2</td>
   </tr>
   <tr>
       <td>col1</td>
       <td>col2</td>
   </tr>
<table>

This is the classical XSLT 1.0 solution for such kind of problems:

<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output omit-xml-declaration="yes" indent="yes"/>
    <xsl:strip-space elements="*"/>

    <xsl:param name="prowLimit" select="12"/>

    <xsl:variable name="vTable" select="/*"/>

 <xsl:template match="node()|@*" name="identity">
     <xsl:copy>
       <xsl:apply-templates select="node()|@*"/>
     </xsl:copy>
 </xsl:template>

 <xsl:template match="tr">
  <xsl:if test="position() mod $prowLimit = 1">
    <table>
      <xsl:copy-of select="$vTable/@*"/>
      <xsl:copy-of select=
      ". | following-sibling::tr[not(position() > $prowLimit -1)]"/>
    </table>
  </xsl:if>
 </xsl:template>
</xsl:stylesheet>
