  Make a template that does just that.
<xsl:template name="monotonous">
  <xsl:param name="str" select="." />
  <xsl:value-of select="$str" />
  <xsl:if test="string-length() = 0">
    <xsl:text>&nbsp;</xsl:text>
  </xsl:if>
</xsl:call-template>

and then you have

<td>
  <xsl:call-template name="monotonous" />
</td>

  I don't think you need to explicitly pass the parameter because of the 
default value, but play with it to make sure.  You may need to include the line
<xsl:with-param name="str" select="." />
but I hope not.
