@garyb The OP is talking about the C I headers. Acrobat is treating it as a column border or graphic object rather than the letter I. I am suspecting because it is a san-serif font and no surrounding text. @smolkabbage I would ask though, are your plans to make this accessible? If so, you will need to make this into a proper table to be compliant. OCR is just the first step. Alternatively you could add the letters I you need behind the image manually so you can build the table structure correctly. It is a fair bit of work for sure.
