XSL-FO Move cell to the next row when there is already a specific number of cells in the row

Question

I need to create a table, where is 12 columns and could be many rows. Now i have something like this:

And I would like to have something like this:

However finally it won't necessary will by multiplicity of twelves in a row, it could be partial filled.

My test xml (actually I create the data structure from scratch, so if necessary, I can slightly modify it):

        <ColsNo>14</ColsNo>
        <Fines>
            <Fine>
                <No>1</No>
                <Price>100</Price>
            </Fine>
            <Fine>
                <No>2</No>
                <Price>200</Price>
            </Fine>
            <Fine>
                <No>3</No>
                <Price>300</Price>
            </Fine>
              ...
            <Fine>
                <No>14</No>
                <Price>1400</Price>
            </Fine>
       </Fines>

My xsl so far:

 <fo:table width="100%" table-layout="fixed" margin-left="2pt" margin-right="2pt">

    <fo:table-column column-width="7cm" border-style="solid" border-width="0.5px"/>
    <xsl:variable name="n" select="count(Fines/Fine)" />
    <xsl:for-each select="Fines/Fine">                                          
        <fo:table-column column-width="auto" border-style="solid" border-width="0.5px"/>
    </xsl:for-each>                                     

    <!-- generate 12 cols -->                                       
    <!--
     <xsl:variable name="nodes" select="//node() | //namespace::* | //comment() | //processing-instruction()" />
    <xsl:for-each select="$nodes[position() &lt; 13]"> 
        <fo:table-column column-width="auto" border-style="solid" border-width="0.5px"/>

    -->

I figure out how to create 12 cols in loop (a bit weird but ok) but I don't know how to move this redundant cells to new row.
