import 'package:flutter/material.dart';

class CustomTable extends StatelessWidget {
  const CustomTable({Key? key}) : super(key: key);

  
  Widget build(BuildContext context) {
    _ItemBean title = _ItemBean("姓名", "年龄", "性别", "单位名称", "单位地点");
    _ItemBean m = _ItemBean("周", "20", "男", "得意", "武汉");
    _ItemBean kg = _ItemBean("王", "18", "男", "中科", "武汉");
    _ItemBean s = _ItemBean("李", "18", "男", "互动", "武汉");
    _ItemBean a = _ItemBean("菜", "18", "男", "阿里", "武汉");
    _ItemBean k = _ItemBean("热", "18", "男", "字节", "武汉");
    _ItemBean mol = _ItemBean("赵", "18", "女", "腾讯", "武汉");
    _ItemBean cd = _ItemBean("曹", "18", "男", "盛天", "武汉");

    List<_ItemBean> data = [title, m, kg, s, a, k, mol, cd];

    return SingleChildScrollView(
      scrollDirection: Axis.horizontal,
      child: Table(
        columnWidths: const <int, TableColumnWidth>{
          0: IntrinsicColumnWidth(),//可以根据内部组件大小自适应宽度
          1: FixedColumnWidth(80.0),
          2: FixedColumnWidth(80.0),
          3: FixedColumnWidth(80.0),
          4: FixedColumnWidth(80.0),
        },
        defaultVerticalAlignment: TableCellVerticalAlignment.middle,
        border: TableBorder.all(
            color: Colors.red, width: 1.0, style: BorderStyle.solid),
        children: data
            .map((item) => TableRow(children: <Widget>[
                  Center(
