有没有一种方法可以根据Flutter中的可用空间来自动调整Table小部件的行高？

Question

我一直在尝试使用Table小部件在Flutter中创建一个表，并使其扩展到屏幕底部，而无需滚动查看整个表。但是，“文本”小部件似乎将行强制具有特定的高度，从而导致最后一行溢出。

[一个有趣的旁注是，表所在的扩展小部件不会溢出屏幕，因此即使表溢出了扩展小部件也不会显示错误消息。相反，似乎表格在“扩展”小部件内溢出。

示例代码：

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter table example',
      home: Scaffold(
        appBar: AppBar(
          title: Text('Flutter table example'),
        ),
        body: Column(
          children: <Widget>[
            Padding(
              padding: const EdgeInsets.all(4.0),
              child: Image.network('https://imgs.xkcd.com/comics/minifigs.png'),
            ),
            Expanded(
              child: Container(
                padding: const EdgeInsets.all(6.0),
                child: Table(
                  columnWidths: {
                    0: FlexColumnWidth(1),
                    1: FlexColumnWidth(2),
                    2: FlexColumnWidth(2),
                  },
                  border: TableBorder(
                      horizontalInside: new BorderSide(color: Colors.grey[300], width: 1)
                  ),
                  defaultVerticalAlignment: TableCellVerticalAlignment.middle,
                  children:
                  List<TableRow>.generate(10, (int i){
                    return TableRow(
                        children: [
                          Padding(
                            padding: const EdgeInsets.all(8.0),
                            child: Text(
                              (1990 + i).toString(),
                              style: TextStyle(
                                fontWeight: FontWeight.bold,
                                fontSize: 14,
                              ),
                            ),
                          ),
                          Padding(
                            padding: const EdgeInsets.all(8.0),
                            child: Text(
                              'Normal people',
                              textAlign: TextAlign.center,
                            ),
                          ),
                          Padding(
                            padding: const EdgeInsets.all(8.0),
                            child: Text(
                              'Lego people',
                              textAlign: TextAlign.center,
                            ),
                          ),
                        ]
                    );
                  }),
                ),
              ),
            )
          ],
        ),
      ),
    );
  }
}

和输出：
