问题 Hey everyone, I am working on parsing the PDF content stream to be able to read and handle annotation operators and also to add these.

Note: I've read a fair amount of the PDF Reference from Adobe, and mostly understand the concept of the file being an object tree, yet I don't understand how to go about figuring out if an

问题 I have a very deep row in a pdfptable. The columns in the left-hand side of this row contain a sub table which has many rows within it. I would like the deep row to split onto more than one page if it is too deep to fit on one page. I can set SplitLate to false to ensure that the row splits. However, the data for the deep columns on the right hand side only shows on the first page and I would like it to be repeated on the second page. A bit of investigation suggested that I could use a cell
