模糊知识点

1. 通过使用 inline 关键字，我们告诉编译器，在每个源文件中只需要保留一个 cTable 的实例，这样就避免了重定义错误

也理解为

inline关键字的作用类似于函数内联，它告诉编译器可以在多个源文件中共享同一个变量实例。

在infos.h中使用inline定义QVector\<CTable\> cTable是为了确保在多个源文件中包含该头文件时，对cTable的定义不会引起重定义错误

1. void QTableView::resizeRowsToContents() 方法可以根据QTableWidgetItem中的文本内容自动调整行高，以确保所有的文本都能够完整显示

• 当你在单元格中使用QTableWidgetItem时，它会自动计算文本的大小并将其显示在单元格中。

  • 调用resizeRowsToContents()方法后，表格会遍历每一行，并根据每个单元格中的文本内容的大小来自动调整行高。

如果单元格是QWidget,resizeRowsToContents()会根据内容的最小高度自动设置单元格的行高
