一个基础的DataTable需要设置columns列,rows行 由于DataTable本身是不具备滑动属性,所以当数据比较多的时候需要嵌套滑动组件,这里我们使用两个SingleChildScrollView来完成纵向横向的滑动 1601631902(1).png classTypeBean{constTypeBean({this.name});finalString name;}classStudentGradesBean{String name;int studentId;i...
1.在DataTable小部件中给予dataRowHeight属性。
source是来自DataTableSource类的数据源;主要实现四个抽象方法,分别是getRow()根据索引获取行内容、rowCount数据源行数、isRowCountApproximate行数是否确定以及selectedRowCount选中的行数(并非选中数组而是选中数量); class _PaginatedPageState extends State<PaginatedDataTablePage> { DataTableSource _sourceData = Source...
1 DataTable 数据表显示原始数据集。它们通常出现在桌面企业产品中。DataTable Widget实现这个组件 2 构造函数 DataTable({Key key,@required this.columns,this.sortColumnIndex,this.sortAscending = true,this.onSelectAll,this.dataRowHeight = kMinInteractiveDimension,this.headingRowHeight = 56.0,this.horizontal...
The Flutter DataGrid (also known as Flutter DataTable) is used to display and manipulate data in a tabular view. Its rich feature set includes row selection, sorting, column sizing, row-height customization, swiping, and more. It has also been optimized to handle high-frequency, real-time up...
rowCount => _data.length; @override // TODO: implement selectedRowCount int get selectedRowCount => 0; } 在页面中使用PaginatedDataTable:PaginatedDataTable( header: const Center(child: Text("班级花名册")), actions: const [Icon(Icons.edit_note_rounded)], columns: const [ DataColumn(label:...
dataRowHeight: 36.0, columns: dataColumns, // 列名 rows: dataRows, // 数据 ), ) ], ), ), ``` 使用SingleChildScrollView,设置Axis.horizontal实现表格左右滑动,DataTable是Flutter专门用来展示表格数据类似于Excel,功能比较多,像排序,全选,单选,点击,上下左右翻页等具备,详细使用请自行查看。

在Flutter中,要实现DataTable的无限滚动,可以使用ListView.builder来构建一个可滚动的DataTable。下面是一个示例代码: 代码语言:txt 复制 import 'package:flutter/material.dart'; class InfiniteDataTable extends StatefulWidget { @override _InfiniteDataTableState createState() => _InfiniteDataTableState(); } c...
