Question

In any case, in order not to display row and column changes (2 arrows and a cross) when editing the table. I went through the W3C project for content content, and it does not say anything about specific cases of different elements.

Answer 1

Found the answer in another Javascript thread , Firefox: how to disable certain browser core controls?

Answer 2

If you understand correctly, then this will be done in Firefox (note: apparently, the document must be loaded before this command is executed. See comments below):

 document.execCommand("enableInlineTableEditing", null, false);

. : Javascript, Firefox: ?
