1. Create new PHP web page. 2. DnD HTML table to the editor. 3. Type 1000 for rows and 1000 for columns in Insert Table dialog. 4. Press OK. Result: after minutes of not responding, java.lang.OutOfMemoryError: Java heap space comes. It's definitely not a typical case, but, in my opinion, performance should be increased, and OutOfMemory error should be handled more carefully.
This issue is not PHP specific. reassigning to HTML
