{#- chirp-ui: Table component
    Responsive table with header configuration and row helper.

    Usage:
        from "chirpui/table.html" import table, row

        Slot-based (complex rows):
        call table(headers=["Name", "Email", "Role"])
            row("Alice", "alice@example.com", "Admin")
            row("Bob", "bob@example.com", "User")
        end

        Data-driven (alignment flows to all cells automatically):
        table(headers=["Name", "Status", "Count"],
              rows=[("Alice", "Active", "42"), ("Bob", "Idle", "7")],
              align=["left", "center", "right"])

        Per-column alignment (slot-based, auto-inherited):
        call table(headers=["Name", "Status", "Count"],
                   align=["left", "center", "right"])
            row("Alice", "Active", "42")
        end

        Column widths (CSS values or proportions):
        call table(headers=["Name", "Status"],
                   widths=["2fr", "1fr"])

        Slots: caption (table caption), row_actions (header cell for actions column).
        Sortable headers:
        call table(headers=["Name", "Email"], sortable=true,
                   sort_url="/users", hx_target="#user-table")
            row(user.name, user.email)
        end
        Row with actions: pass row_actions(...) as last cell when actions_header=true
        Sticky header:
        call table(headers=[...], sticky_header=true)
