import QtQuick 2.15 import QtQuick.Controls 2.15 ApplicationWindow { visible: true width: 400 height: 300 GridView { width: parent.width height: parent.height cellWidth: 100 cellHeight: 30 columnCount: 2 delegate: Text { text: model.name + " - " + model.age width: 100 height: 30 } model: ListModel { ListElement { name: "John"; age: 25 } ListElement { name: "Alice"; age: 30 } ListElement { name: "Bob"; age: 35 } } } } 运行显示 Cannot assign to non-existent property "columnCount"

很抱歉，我之前给出的代码存在一些问题。在QML中，GridView没有columnCount属性来指定列数。相反，GridView会根据提供的model自动计算列数。以下是修正后的代码示例：

import QtQuick 2.15
import QtQuick.Controls 2.15

ApplicationWindow {
    visible: true
    width: 400
    height: 300

    GridView {
        width: parent.width
        height: parent.height
        cellWidth: 100
        cellHeight: 30

        delegate: Text {
            text: model.name + " - " + model.age
            width: 100
            height: 30
        }

        model: ListModel {
            ListElement { name: "John"; age: 25 }
            ListElement { name: "Alice"; age: 30 }
            ListElement { name: "Bob"; age: 35 }
        }
    }
}

这样，你可以使用GridView来创建一个简单的表格，并在每个单元格中显示姓名和年龄的信息。
