我正在使用XSL FO将XML数据从文件转换为呈现为PDF文档的表格。如果XML中没有数据，我被要求渲染空表结构 - 将表体留空。
我尝试了以下代码
<!-- Addresses -->
<fo:table border="1px solid black" table-layout="fixed" width="100%">
<fo:table-column column-width="2in"/>
<fo:table-column column-width="2in"/>
<fo:table-column column-width="2.5in"/>
<fo:table-column column-width="2.5in"/>
<fo:table-column column-width="2in"/>
<fo:table-header>
<fo:table-row>
<fo:table-cell border="0.1pt solid black" text-align="left" font-size="12pt" font-weight="bold" number-columns-spanned="5" background-color= "#B6B6B4"><fo:block>Addresses</fo:block></fo:table-cell>
</fo:table-row>
<fo:table-row>
<fo:table-cell border="0.1pt solid black" text-align="left" font-size="10pt" font-weight="bold">
<fo:block> Address Type </fo:block>
</fo:table-cell>
<fo:table-cell border="0.1pt solid black" text-align="left" font-size="10pt" font-weight="bold">
<fo:block> Fields</fo:block>
</fo:table-cell>
<fo:table-cell border="0.1pt solid black" text-align="left" font-size="10pt" font-weight="bold">

但是这段代码没有按预期工作。 请问这里的专家请问是否有办法在XSL FO中实现所需的行为？ “core / clientMain / coverage”是xsl模板。
答案 0 :(得分：0)
根据您呈现的代码，“离开桌面空间”是什么意思有点不清楚。当然，我可以相信，在XPath表达式core/clientMain/coverage求值为空节点集的情况下，它不会执行您想要的操作，因为它将在<fo:table-body>元素内生成单个{{1子元素，没有任何干预<fo:table-cell>。
我可以看到你想要产生一排空单元格（显然其中五个与五个标题匹配），或者根本没有行，但是你所呈现的内容没有意义。
所有情况下的无行都很简单：只需省略第二个<fo:table-row>元素及其内容，只留下
xsl:if（我认为当事实上有数据时，该部分按预期工作。）
如果实际上您想提供一个空数据行，那么提供它！详细信息取决于您的具体需求，但可能如下所示：
<xsl:if test="core/clientMain/coverage">
<xsl:apply-templates select="core/clientMain/coverage"/>
</xsl:if>
