无限 table 循环；行内容大于页面（例如因为您没有缩放图像）

Question

我使用 Itext 库将 html 中的 table 转换为 pdf 并出现 "Infinite table loop; row content is larger than the page (for instance because you didn't scale an image)" 错误。请在下面找到我的代码。

public static File createPDF(File outputDir, Context context) {
    Document document = null;
    String htmlStr = "<table><tr><td><div class="two-col-pair-one"><div align="center">1:  9_ITEM</div><div class="row-odd">
<div class="packet-font">
<div class="two-col">Cust. Name</div>
<div class="two-col">Gg</div>
</div>
<div style="clear:both"></div>
</div>
<div class="row-even">
<div class="packet-font">
<div class="two-col">Org. City</div>
<div class="two-col">D</div>
</div>
<div style="clear:both"></div>
</div>
<div class="row-odd">
<div class="packet-font">
<div class="two-col">Dest. City</div>
<div class="two-col">D</div>
</div>
<div style="clear:both"></div>
</div>
<div class="row-even">
<div class="packet-font">
<div class="two-col">Product Type</div>
<div class="two-col">Domestic Moving</div>
</div>
<div style="clear:both"></div>
</div>
<div class="row-odd">
<div class="packet-font">
<div class="two-col">Trans.Mode</div>
<div class="two-col">Road</div>
</div>
<div style="clear:both"></div>
</div>
<div class="row-even">
<div class="packet-font">
<div class="two-col">Description</div>
<div class="two-col">Fridge - Regular</div>

手动设置table单元格高度时出现同样的错误。

理想情况下，单元格应移至下一页，但 itext 5 无法处理。

ITEXT 7解决了这个问题。
