I wonder whether any technique exists in LaTeX to make some parts non-renderable, for example, the contents in tabular data? Of course, if someone wants to recognize the texts (say from a table) using various OCR software programs, I do not want to readily recognize the text. Thank you.

I guess that by non-renderable you mean it can't be copied as text rom the resulting output (e.g. PDF) file. You could run the special part seperately through LaTeX and convert it to a bit-map image, e.g. a PNG file, and include that in your final document. – Pieter van Oostrum Aug 27 '22 at 09:27

What is the use case exactly, why do you want the text to be uncopyable/unrecognizable? – Marijn Aug 27 '22 at 14:44

How "unrecognizable" do you want it? Maybe https://ctan.org/pkg/censor? – Steven B. Segletes Aug 27 '22 at 19:57

Thank you @StevenB.Segletes, for your comment. But I want the text to be visible but 'not-copyable.' – relinquere Aug 28 '22 at 02:01

Thank you, @Marijn, I want some tabular data as 'not-copyable' in a document, whereas all texts except the table are copyable. – relinquere Aug 28 '22 at 02:05

Thank you, @PietervanOostrum, I desire something directly from .tex to .pdf file. – relinquere Aug 28 '22 at 02:07

@relinquere I understand what you want to do, but I asked for the reason why you want to do that. Knowing the reason can help us to give you advice if and how you can meet your (end) goal. – Marijn Aug 28 '22 at 06:51
