The current behavior with tables in Deepdwn is that all cells are left-aligned, even when a column is identified as center-aligned (:---:) or right-aligned (----:). It’s impossible to align cells manually. I don’t mind not being able to align cells manually, but it’s desired that cell content would be aligned to a more expected location in the cell.

Thanks for your feedback.

This is a planned feature and may make it into one of the next releases
