Type TableHeader
type TableHeader struct {
ID ui.ID
Label string
Sort TableSortDirection
Disabled bool
// FocusableWhenDisabled lets a header retain keyboard focus while its
// application is refreshing. Activation is still disabled.
FocusableWhenDisabled bool
Description string
}TableHeader describes one header cell. A non-zero ID makes it sortable and keyboard-activatable; a zero ID remains an ordinary text heading. Description optionally localizes the accessible sort-state description (the default is English). Disabled headers keep their direction visible but cannot activate.
