在React 中实现虚拟化表格的基本代码示例如下: importReactfrom'react';import{FixedSizeListasList}from'react-window';constRow=({index,style})=>(<div style={style}>Row{index}</div>);constMyTable=({rowCount})=>(<List height={600}

实际上,vbptr 指的是虚基类表指针(virtual base table pointer),该指针指向了一个虚基类表(virtual table),虚表中记录了虚基类与本类的偏移地址;通过偏移地址,这样就找到了虚基类成员,而虚继承也不用像普通多继承那样维持着公共基类(虚基类)的两份同样的拷贝,节省了存储空间。
