SAP UI5 响应式表格 sap.m.Table 根据不同宽度的屏幕动态决定显示或隐藏 Column 的实现源代码讲解试读版
                C/C++ Qt TableWidget 表格组件应用
            
TableWidget 表格结构组件，该组件可以看作是TreeWidget树形组件的高级版，表格组件相比于树结构组件灵活性更高，不仅提供了输出展示二维表格功能，还可以直接对表格元素直接进行编辑与修改操作，表格结构分为表头，表中数据两部分，表格结构可看作一个二维数组，通过数组行列即可锁定特定元素，如下代码是针对表格结构的基本使用方法，分别实现了表头数据的初始化，元素的插入等基本操作。
