【问题标题】:Best Way to Create Table In Flutter在 Flutter 中创建表格的最佳方法
【发布时间】:2022-01-12 04:01:12
【问题描述】:

在这里,我使用容器创建表,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格,任何人都可以给我建议吗?

代码如下:

_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,
          ),
        ),
      ),
    );
  }

然后对于我在行内使用 flex 的内容。你对这个有什么建议吗?

    【解决方案1】:

    您可以使用 TableData Table

    在 Flutter 中创建表格
    1. 使用表类:

    参考Tablehere

    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 类的结果屏幕->

    1. 使用DataTable 类:

    参考DataTablehere

    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*'),
            ),
          ],
        ),
      ],
    ),

    您也可以参考thisTable

      【解决方案2】:

      Flutter 为此提供了一个 Table 类(但您也可以使用简单的 Row + Column 组合来实现)。

      这里是表格文档的链接:Flutter Table

      Container(
              color: Colors.white,
              padding: EdgeInsets.all(20.0),
              child: Table(
                border: TableBorder.all(color: Colors.black),
                children: [
                  TableRow(children: [
                    Text('Cell 1'),
                    Text('Cell 2'),
                    Text('Cell 3'),
                  ]),
                  TableRow(children: [
                    Text('Cell 4'),
                    Text('Cell 5'),
                    Text('Cell 6'),
                  ])
                ],
              ),
            )
