我没有找到如下的明确问题：
我想在XSL-FO中将XML转换为PDF保留tabspace（ASCII 009）。
我的<fo:block />看起来像这样：
<fo:block linefeed-treatment="preserve" white-space-collapse="false" white-space-treatment="preserve">
<xsl:value-of select="orderText" />
</fo:block>
使用此配置，我可以保留换行符和普通空格，但不保留制表符空间。我在这篇文章中尝试了很多属性：https://github.com/xunit/xunit/issues/416 但它仍然无法奏效。如果我加入这个：
Forename: John
Surname: Smith
我明白了：
Forename: John
Surname: Smith
有关信息：
在我的XSL-FO中，我使用Layout-Master格式化页面。也许这可能是问题所在。 这是完整的XSL文件。

XSL-FO不处理除空格之外的选项卡。选项卡没有特定宽度，并且块中没有定义“制表位”。
XSL-FO中的定位是通过块和位置属性完成的。它看起来像你想要的，是使用一个额外的列并将值拆分为2：一个单元格中的第一部分，另一个单元格中的第二部分。
