xsl-fo:table中基于列值的动态行数跨度

Question

嗨，我正试图根据第二列中的值对单元格进行分组，使用此功能使用apache FOP 创建PDF

我的代码是

document.xml

<data>
<data-body>
<table-header>
<column-one>Column One</column-one>
<column-two>Column Two</column-two>
<column-three>Column Three</column-three>
<column-four>Column Four</column-four>
</table-header>
<table-data>
<column-one>One</column-one>
<column-two>5000</column-two>
<column-three>Three</column-three>
<column-four>Four</column-four>
</table-data>
<table-data>
<column-one>One</column-one>
<column-two>5000</column-two>
<column-three>Three</column-three>
<column-four>Four</column-four>
</table-data>
<table-data>
<column-one>One</column-one>
<column-two>1200</column-two>
<column-three>Three</column-three>
<column-four>Four</column-four>
</table-data>
<table-data>
<column-one>One</column-one>
<column-two>2000</column-two>
<column-three>Three</column-three>
<column-four>Four</column-four>
</table-data>
<table-data>
<column-one>One</column-one>
<column-two>2000</column-two>
<column-three>Three</column-three>
<column-four>Four</column-four>
</table-data>
</data-body>
</data>

对于一个特定的列，如果5000在同一列中重复，我需要按顺序合并重复的值我需要根据值在一个单元格中动态合并5000

我还尝试了**xsl:for-each group**group neighbor="column two">，column-grouping-key((但它不像我预期的那样分组，请帮忙，提前谢谢。

我认为您想要使用group-adjacent，然后需要传递组项的计数和当前组索引来填充number-rows-spanned属性并阻止相邻组中任何第二个column-two单元格的输出：
