TableContentScope

The receiver of a Table's content, through which it configures the parts the table builds itself.

A JTable builds its header itself; Header configures it. An if/else can select its declaration while keeping the same header:

Table(rows = people, columns = { column("Name") { it.name } }) {
    if (compact) {
        Header(modifier = SwingModifier.background(surface), reorderingAllowed = false)
    } else {
        Header(modifier = SwingModifier.background(surfaceVariant))
    }
}

A table holds nothing besides its parts, so a child that declares none of them is refused, naming the table and the calls that would place it. Each part is declared once: two Headers are refused too. A part whose declaration goes away gets back the values its declaration replaced.
