flutter - 在 Flutter 中创建表的最佳方法

Question

在这里，我使用容器创建表格，并基于使用弹性编号进行扩展，以使标题和行相关。我认为这不是最好的方法，但我不知道如何创建这样的表，任何人都可以给我一个建议吗？

这是代码:

_tableSection

Widget _bookingListSection(OnlineBookingListController controller) {
    return Column(
      children: [
        _buildHeaderTable(),
        Expanded(
          child: ListView.builder(
            padding: EdgeInsets.zero,
            itemCount: controller.listBooking.length,
            itemBuilder: (context, index) {
              int lastIndex = controller.listBooking.length - 1;

              return _buildContentTable(
                index,
                lastIndex,
                context,
                controller,
              );
            },
          ),
        ),
      ],
    );
  }

_buildHeaderTable(),

Widget _buildHeaderTable() {
    return Container(
      width: double.maxFinite,
      height: AppSize.DIMEN_64.h,
      padding: EdgeInsets.fromLTRB(
        AppSize.DIMEN_22.h,
        AppSize.DIMEN_16.h,
        AppSize.DIMEN_22.h,
        AppSize.DIMEN_16.h,
      ),
      decoration: BoxDecoration(
        color: AppColors.GREY_BLACK_BACKGROUND,
        borderRadius: BorderRadius.only(
          topLeft: Radius.circular(AppSize.RADIUS_8.h),
          topRight: Radius.circular(AppSize.RADIUS_8.h),
        ),
      ),
      child: Row(children: [
        _titleHeaderTable('Time', 3),
        _titleHeaderTable('Phone Number', 3),
        _titleHeaderTable('Customer Name', 3),
        _titleHeaderTable('Room', 3),
        _titleHeaderTable('Waitress', 3),
        _titleHeaderTable('Status', 2),
        _titleHeaderTable('Action', 4),
      ]),
    );
  }

Widget _titleHeaderTable(String title, int flexNum) {
    return Expanded(
      flex: flexNum,
      child: Container(
        child: Text(
          title,
          textAlign: TextAlign.left,
          maxLines: 2,
          style: textStyleW700S14.copyWith(
            color: AppColors.WHITE,
          ),
        ),
      ),
    );
  }

然后对于内容我在行内使用flex。您对此有什么建议吗？

您可以使用Table和Data Table在Flutter中创建Table

1. 使用表类:

引用Table类here

Container(
  margin: EdgeInsets.all(20),
  child: Table(
    defaultColumnWidth: FixedColumnWidth(120.0),
    border: TableBorder.all(
        color: Colors.black, style: BorderStyle.solid, width: 2),
    children: [
      TableRow(children: [
        Column(
          children: [
            Text(
              'Website',
              style: TextStyle(fontSize: 20.0),
            ),
          ],
        ),
        Column(
          children: [
            Text(
              'Tutorial',
              style: TextStyle(fontSize: 20.0),
            ),
          ],
        ),
        Column(
          children: [
            Text(
              'Review',
              style: TextStyle(fontSize: 20.0),
            ),
          ],
        ),
      ]),
      TableRow(children: [
        Column(
          children: [
            Text('https://flutter.dev/'),
          ],
        ),
        Column(
          children: [
            Text('Flutter'),
          ],
        ),
        Column(
          children: [
            Text('5*'),
          ],
        ),
      ]),
      TableRow(children: [
        Column(
          children: [
            Text('https://dart.dev/'),
          ],
        ),
        Column(
          children: [
            Text('Dart'),
          ],
        ),
        Column(
          children: [
            Text('5*'),
          ],
        ),
      ]),
      TableRow(children: [
        Column(
          children: [
            Text('https://pub.dev/'),
          ],
        ),
        Column(
          children: [
            Text('Flutter Packages'),
          ],
        ),
        Column(
          children: [
            Text('5*'),
          ],
        ),
      ]),
    ],
  ),
),

使用Table Class-> 的结果屏幕

使用DataTable类:

引用DataTable类here

DataTable(
  columns: const <DataColumn>[
    DataColumn(
      label: Text(
        'Sr.No',
        style: TextStyle(
          fontWeight: FontWeight.bold,
        ),
      ),
    ),
    DataColumn(
      label: Text(
        'Website',
        style: TextStyle(
          fontWeight: FontWeight.bold,
        ),
      ),
    ),
    DataColumn(
      label: Text(
        'Tutorial',
        style: TextStyle(
          fontWeight: FontWeight.bold,
        ),
      ),
    ),
    DataColumn(
      label: Text(
        'Review',
        style: TextStyle(
          fontWeight: FontWeight.bold,
        ),
      ),
    ),
  ],
  rows: const <DataRow>[
    DataRow(
      cells: <DataCell>[
        DataCell(
          Text('1'),
        ),
        DataCell(
          Text('https://flutter.dev/'),
        ),
        DataCell(
          Text('Flutter'),
        ),
        DataCell(
          Text('5*'),
        ),
      ],
    ),
    DataRow(
      cells: <DataCell>[
        DataCell(
          Text('2'),
        ),
        DataCell(
          Text('https://dart.dev/'),
        ),
        DataCell(
          Text('Dart'),
        ),
        DataCell(
          Text('5*'),
        ),
      ],
    ),
    DataRow(
      cells: <DataCell>[
        DataCell(
          Text('3'),
        ),
        DataCell(
          Text('https://pub.dev/'),
        ),
        DataCell(
          Text('Flutter Packages'),
        ),
        DataCell(
          Text('5*'),
        ),
      ],
    ),
  ],
),

使用 DataTable Class-> 的结果屏幕

您可以引用this也适用于 Table
