First - clarification
@deshmukh as @amreus suggests below we can use multiple columns. I would have suggested it myself. In some ways the raw requirement is to increase the density of the information displayed within a tiddler. On wide screens we see the opportunity to extend the display of content in the horizontal direction.
A possible solution?
Modern websites now tend to avoid tables for the presentation of data that may need to vary in layout depending on different devices, that is responsive design. The strategy is to make use of flexboxes and other design methods. Then if the tiddler is wide it would automatically make use of more columns or reduce to one on a mobile.
