backgroundDecoration property
The SpanDecoration to paint behind the content of this span.
The backgroundDecorations of the TableView.mainAxis are painted after the backgroundDecorations of the other Axis. On top of that, the content of the individual cells in this span are painted, followed by any specified foregroundDecoration.
The decorations of pinned rows and columns are painted separately from the decorations of unpinned rows and columns, with the unpinned rows and columns being painted first to account for overlap from pinned rows or columns.
