我在创建PDF时尝试使用Fo.Net执行渲染时收到此错误（标题）。
[MethodImpl(MethodImplOptions.Synchronized)]
public static void MakePdf(XmlDocument xslFoDocument, Stream outputStream)
{
FonetDriver driver = PdfPrinterDriver.InitFonetDriver();
driver.Render(xslFoDocument, outputStream);
}
我发现了关于这个主题的另一篇文章（对于Java而不是C＃，因为我正在使用，但我认为它是相同的错误，原因相同）：At least one of minimum, optimum, or maximum IPD must be specified on table - XSL-FO Apache FOP。问题是，我无法在xsl文件中的任何位置找到未设置大小的位置。谁知道可能出错了什么？下面是完整的XSL样式表文件
编辑：进一步故障排除后，我设法本地化表，导致抛出异常。我仍然无法看到我在哪里错过了宣称的大小。

我将此标记为对@lfurini的第一条评论的回答和引用。至于最后一个问题@lfurini，当我以为我已经设置了表格宽度时，我正在查看错误的表格。所以总结其他人也对此感到疑惑;如果宽度在fo：table中设置，它足以在其中一列上设置宽度，其余的将调整。
