Of course.

<xsl:template match="years">
  <tr>
    <xsl:call-template name="split_years">
      <xsl:with-param name="year_list" select="text()"/>
    </xsl:call-template>
  </tr>
</xsl:template>

<xsl:template name="split_years">
  <xsl:param name="year_list"/>
  <xsl:choose>
    <!-- if there's a comma, take everything before it... -->
    <xsl:when test="contains($year_list,',')">
      <xsl:variable name="year" select="normalize-space(substring-before($year_list,','))"/>
      <!-- only make a table cell if there is non-whitespace before the comma -->
      <xsl:if test="$year">
        <td>
          <xsl:value-of select="$year"/>
        </td>
      </xsl:if>
      <!-- ...then go process everything after it -->
      <xsl:call-template name="split_years">
        <xsl:with-param name="year_list" select="substring-after($year_list,',')"/>
      </xsl:call-template>
    </xsl:when>
    <!-- if there's no comma, but something besides whitespace -->
    <xsl:when test="normalize-space($year_list)">
      <td><xsl:value-of select="$year_list"/></td>
    </xsl:when>
    <!-- otherwise, $year_list must be empty, so do nothing-->
  </xsl:choose>
</xsl:template>
