I don't have the time th check this, but the sollution should be
somewhat along the line of:

<template match="table">
  <variable name="max_cols">
    <call-template name="count_cols_per_row">
      <with-param name="row">
        <value-of select="count(row)"/>
      </with-param>  
    </call-template>
  </variable>  
  <!-- do your processing here -->
</template>

<tempalte name="count_cols_per_row">
  <param name="row">0</param>
  <param name="max_cols">0</param>

  <choose>
    <when test="row &gt; 0">
      <variable name="cols">
        <value-of select="count(row[$row]/col)"/>
      </variable>
      <variable name="max">
        <choose>
          <when test="$max_cols %lt; $cols">
            <value-of select="$cols"/>
          </when>
          <otherwise>
            <value-of select="$max_cols"/>
          </otherwise>
        </choose>  
      </variabe> 
      <call-template name="count_cols_per_row">
        <with-param name="row">
          <value-of select="$row - 1"/>
        </with-param>
        <with param name="max_cols">
          <value-of select="$max"/>
        </with-param>
      </call-template>
    </when>
    <otherwise>
      <value-of select="$max_cols"/>
    </otherwise>  
  </choose>
</template>  

This should to the trick, it can for sure be optimized and now has about
O(rows) runtime.

Cu,
    Goetz.
