I tried to merge cells in the table in obsidian.
I cannot find a way to do that. If I need to install other plugins, which plugin should I install?
If you want to do it natively without any plugins, you have to use html tables; Markdown tables cannot be merged natively.
For plugins;
I have only tried the first one before, and it used to make the cells max size.
The second requires you to insert tables via code blocks.
Have you tried searching for plugins within Obsidian?
Simply searching “tables” or “merge” should give you a starting point.
