CALS表格PDF视图边框缺失，如何用XSLT处理rowsep/colsep属性？

Hey there! Let's tackle how to make those table borders show up correctly in your PDF, even with frame="none" set on your CALS table. The rowsep and colsep attributes are key here—they control whether individual cell borders are visible, and we can map them directly to XSL-FO (since you're generating PDF) border properties.

First, a quick recap of what these attributes do #

• rowsep="1": The cell should display a bottom border (separating it from the row below). rowsep="0" hides this border.
• colsep="1": The cell should display a right border (separating it from the next column). colsep="0" hides this border.

XSLT Template to Handle Borders #

Since you're working with XSL-FO for PDF, here's a practical template that processes each <entry> element and applies borders based on these attributes:

<xsl:template match="entry">
  <fo:table-cell>
    <!-- Set bottom border based on rowsep -->
    <xsl:attribute name="border-bottom">
      <xsl:choose>
        <xsl:when test="@rowsep = '1'">solid 1pt #000</xsl:when>
        <xsl:otherwise>none</xsl:otherwise>
      </xsl:choose>
    </xsl:attribute>

    <!-- Set right border based on colsep -->
    <xsl:attribute name="border-right">
      <xsl:choose>
        <xsl:when test="@colsep = '1'">solid 1pt #000</xsl:when>
        <xsl:otherwise>none</xsl:otherwise>
      </xsl:choose>
    </xsl:attribute>

    <!-- Optional: Add top border for the first row of thead -->
    <xsl:if test="parent::row[position() = 1 and ancestor::thead]">
      <xsl:attribute name="border-top">solid 1pt #000</xsl:attribute>
    </xsl:if>

    <!-- Optional: Add left border for the first column -->
    <xsl:if test="position() = 1">
      <xsl:attribute name="border-left">solid 1pt #000</xsl:attribute>
    </xsl:if>

    <!-- Render cell content -->
    <fo:block>
      <xsl:apply-templates/>
    </fo:block>
  </fo:table-cell>
</xsl:template>

Key Notes for Edge Cases #

• Cross-row cells (morerows): If an entry has @morerows="n", adjust the bottom border logic to only show it on the last row the cell spans:

  <xsl:when test="@rowsep = '1' and (not(@morerows) or parent::row[position() = current()/@morerows + 1])">
    solid 1pt #000
  </xsl:when>
  

• Customize border styles: Tweak solid 1pt #000 to match your desired thickness, style (dashed, dotted), and color.
• Table-level border override: Ensure your root <fo:table> element has border="none" to respect the frame="none" setting from your CALS XML.

Final Checks #

Wrap this template into your existing XSL-FO stylesheet, make sure your main table template outputs an <fo:table> with no outer border, and you'll get a table that strictly follows the rowsep and colsep rules from your original XML.
