I have never understood this feature request. What does it mean word wrap in in markdown tables?
Line wrapping doesn’t make sense because you are gonna get confused in which row of the table you are. Or do you want graphical representation of a table and edit cell by cell? In that case, cell-level line wrapping makes sense. If it’s latter case, please follow this FR https://forum.obsidian.md/t/live-preview-edit-table-cell-by-cell/34110.
Otherwise, please explain what you mean with this FR.
