I wanted to share a custom XSLT that I setup if anyone's interested and also to find out if there's a better way to do this.  I'm outputting the data in two columns by testing the record position and displaying the data in another table that's either left or right aligned.

The pertinent code follows:

  <xsl:template match="udt:Data" mode="list">
    <xsl:if test="position() mod 2 = 1">
      <table border="1" width="50%" align="left">
        <tr>
          <td align="center">
            <xsl:call-template name="EditLink" />
            <xsl:value-of select="udt:Wallpaper" disable-output-escaping="yes" />
            <br />
            <xsl:value-of select="udt:Caption" disable-output-escaping="yes" />
          </td>
        </tr>
      </table>
    </xsl:if>
    <xsl:if test="position() mod 2 = 0">
      <table border="1" width="50%" align="right">
        <tr>
          <td align="center">
            <xsl:call-template name="EditLink" />
            <xsl:value-of select="udt:Wallpaper" disable-output-escaping="yes" />
            <br />
            <xsl:value-of select="udt:Caption" disable-output-escaping="yes" />
          </td>
        </tr>
      </table>
      <br clear="all" />
    </xsl:if>
  </xsl:template>

  <xsl:template match="/udt:UserDefinedTable">
    <xsl:variable name="currentData" select="udt:Data" />
    <table border="1" class="normal" width="100%">
      <tr>
        <td>
          <xsl:apply-templates select="$currentData" mode="list">
          </xsl:apply-templates>
        </td>
      </tr>
    </table>
  </xsl:template>
