if you use
<br>, you get a line wrap inside the cell in edit mode.
@OlivierPS: I use Typora too, and have done so for around 3 years. What you state here is not correct either.
When you put <br> inside a cell you do get a line wrap, but it is NOT in Edit mode. Typora is a WYSIWYG editor, so anything you do is immediately rendered as a Preview mode, although the Preview mode is editable.
If you want the real Edit mode, you have to turn on what Typora calls “Source Code Mode” If you then look at a cell with <br> in it you’ll see it is just as ugly as Obsidian’s Edit mode for tables, with NO lines wrapped. They only get wrapped when you go back to Typora’s normal, WYSIWYG mode.
Furthermore, in Typora’s normal, WYSIWYG mode the <br> tag remains visible in the cell, whereas in Obsidian it disappears when you turn on Preview.
Last but not least, next year Licat will start work on a WYSIWYG mode as a 3rd mode for Obsidian, something I have been eagerly waiting for since I started using Obsidian.
