<xsl:param name="a_name">
  <xsl:choose>
   <xsl:when test="@a_name"><xsl:value-of select="@_name"/></xsl:when>
   <xsl:otherwise>default</xsl:otherwise>
  </xsl:choose>
</xsl:param>

does what you say you are looking for, but it's not what you want.

what you want is

<table bgcolor="#ff0000">
  <xsl:if test="@col1"><xsl:value-of select="@col1"/></xsl:if>
  <tr><td><xsl:apply-templates/></td></tr>
<table>

if your input attribute had had the same name as the result attribute 
it is simpler


<table bgcolor="#ff0000">
  <xsl:copy-of select="@bgcolor"/>
  <tr><td><xsl:apply-templates/></td></tr>
<table>
