Flutter Table的用法

Widget build(BuildContext context) {
  return Table(
    border: TableBorder.all(),
    columnWidths: const <int, TableColumnWidth>{
      0: IntrinsicColumnWidth(),
      1: FlexColumnWidth(),
      2: FixedColumnWidth(64),
    },
    defaultVerticalAlignment: TableCellVerticalAlignment.middle,
    children: <TableRow>[
      TableRow(
        children: <Widget>[
          Container(
            height: 32,
            color: Colors.green,
          ),
          TableCell(
            verticalAlignment: TableCellVerticalAlignment.top,
            child: Container(
              height: 32,
              width: 32,
              color: Colors.red,
            ),
          ),
          Container(
            height: 64,
            color: Colors.blue,
          ),
        ],
      ),
      TableRow(
        decoration: const BoxDecoration(
          color: Colors.grey,
        ),
        children: <Widget>[
          Container(
            height: 64,
            width: 128,
            color: Colors.purple,
          ),
          Container(
            height: 32,
            color: Colors.yellow,
          ),
          Center(
            child: Container(
              height: 32,
              width: 32,
              color: Colors.orange,
            ),
          ),
        ],
      ),
    ],
