Tree Table Support

I’d like to be able to render a tree table like:

**Name**        | **Size** | **Modified**
--------------- | -------- | ----------------------------
file_name_1     | 1 Pibit  | +2024-01-01T00:00:00.0+00:00
    file_name_4 | 2 Pibit  | +2026-01-01T00:00:00.0+00:00
file_name_2     | 0 b      | +2025-01-01T00:00:00.0+00:00

which would render as

does.
