Can anybody suggest why the tables in a PDF generated from a word document spontaneously fall out of the reading order? I am trying to make these PDFs accessible. I put in Alt Texts, check tags, look at the reading order, use the table editor to define the left-hand headers and almost always somewhere in all those activities, a table that was previously in the reading order will just fall out. Only one time have I been able to retag it using the Touch Up Reading Order Tools. All the other times I have had to start from scratch, regenerating the PDF again from the source file. I have tried removing the tables from the source word document and putting them in WORDPAD and then regenerating the PDF, but they still just fall out randomly (as it seems to me).
Any help and suggestions would be much appreciated.
