nonisolated init(_ data: Data, @TableColumnBuilder<TableColumnForEach<Data, ID, RowValue, Sort, Content>.TableRowValue, TableColumnForEach<Data, ID, RowValue, Sort, Content>.TableColumnSortComparator> content: @escaping (Data.Element) -> Content) where ID == Data.Element.ID, Data.Element : Identifiable
```

## Parameters
