Playground demo: Raxol.UI.Components.Table — real component with the three border modes:

• :grid — full box-drawing frame + column + row rules
• :inner — column/row rules only (no outer frame)
• :none — padded content; header_separator toggles the ─ rule

Keys route through Table.handle_event/3. Sort cycles via Table.update({:sort, col}, …) (component has no sort keybinding).
