        { name: "id", title: "ID", width: 60 },
        { 
            name: "name", 
            title: "姓名", 
            width: 100,
            renderer: function(row) {
                return "<b>" + row.name + "</b>";
            }
        },
        { name: "age", title: "年龄", width: 80 },
        { 
            name: "action", 
            title: "操作", 
            width: 120,
            renderer: function(row) {

    ]
}

响应式表格 ​

qml
Components.EAnimatedWindow {
    width: 600
    height: 400
    title: "响应式表格示例"
    visible: true
    
    Column {
        anchors.fill: parent
        padding: 20
        spacing: 16
        
        Text {
            text: "用户数据表格"
            font.pointSize: 20
            font.bold: true
            color: theme.textColor
            anchors.horizontalCenter: parent.horizontalCenter
        }
        
        Components.EDataTable {
            width: parent.width - 40
            height: 300
            columns: [
                { name: "id", title: "ID", width: 60 },
                { name: "name", title: "姓名", width: 100 },
                { name: "age", title: "年龄", width: 80 },
                { name: "email", title: "邮箱", width: 200 },
                { name: "phone", title: "电话", width: 150 }
            ]
            data: [
                { id: 1, name: "张三", age: 25, email: "zhangsan@example.com", phone: "13800138000" },
                { id: 2, name: "李四", age: 30, email: "lisi@example.com", phone: "13800138001" },
                { id: 3, name: "王五", age: 28, email: "wangwu@example.com", phone: "13800138002" },
                { id: 4, name: "赵六", age: 35, email: "zhaoliu@example.com", phone: "13800138003" },
                { id: 5, name: "钱七", age: 22, email: "qianqi@example.com", phone: "13800138004" },
                // 添加更多数据...
            ]
            showPagination: true
            pageSize: 10
            
            onRowClicked: (index, row) => console.log("点击的行:", index, row.name)
        }
    }
}

最佳实践 ​

  1. 数据管理：对于大量数据，考虑使用分页和懒加载策略
  2. 列配置：根据数据类型和重要性合理设置列宽和排序功能
  3. 性能优化：避免在渲染函数中执行复杂的计算或DOM操作
  4. 用户体验：提供清晰的视觉反馈，如悬停效果、选中状态等
  5. 响应式设计：在不同屏幕尺寸下调整表格宽度和列显示

注意事项 ​

  • 表格组件支持虚拟滚动，适合处理大量数据
  • 可以通过renderer函数自定义列的渲染方式
  • 排序功能默认对所有可排序列启用
  • 分页控件会自动根据数据量显示
  • 表格支持键盘导航，使用上下箭头选择行，回车键确认选择
