Error element not allowed when itextsharp exports PDF

When itextsharp is used to export PDF files, an error "element not allowed" is reported.

So I started to check various places and found that there was no problem compared to the demo I wrote before. Finally, I found an error.

Xmlworkerhelper. getinstance (). parsexhtml (writer, Doc, msinput, null, encoding. utf8, new unicodefontfactory (); in this place, check the background,

At the same time, it is normal to write a table test. Therefore, you can only delete nodes and test them one by one. It is found that itextsharp does not support the th tag in the HTML table, so this error is reported.

If TH is changed to the TD tag, the problem is solved. After reading itextsharp, you still need to upgrade it.
