Explicit line breaks in a cell:
| line1<br>line2 | x |
| b | c |
Wide cell content wraps to fit the terminal:
| This is a long cell that should wrap across multiple lines because its content exceeds the eighty column default terminal width used in these render tests. |
Column widths are distributed proportionally, without breaking a short word apart just to make room for a long neighbour:
| short | this cell has quite a lot of content that needs wrapping to fit, unlike its narrow single-word neighbour |
