C++ 如果字段中的字符数不同，则输出时分隔符会丢失

我的格式有问题。我的程序收集关于学生的信息，然后输出用户输入的信息。 结论应该精确地出现在这些列中（我指的是制表法和“| |”）。 问题是，对于不同大小的字段，这些分隔符“| |”对我来说会丢失，而且总体而言，所有这些看起来都很难看。可以做些什么，使所有的东西都能漂亮地展示出来。即使某些字段中的字符数不匹配

如何在Pascal上解决此问题，例如：

write(first.surname:8:6);

输出：

Information you entered >

cout这是一项复杂的任务，没有神奇的解决方案：您需要测量字段的大小（以字符为单位），然后相应地添加空格，等等。
更不用说可能存在的utf-8问题（以字节为单位的字符串大小可能与以字符为单位的大小不同）

您可以使用
std:：setw（）
，但这并不能解决所有问题

你最好使用图书馆。
如果你有C++17可用，似乎是一个相当整洁的解决方案。
对你的要求来说，可能有点过分了

（免责声明：我自己没有使用过。）
选项卡“\t”很可能不起作用。您应该使用头文件中定义的
std:：setw
。任何像样的书、教程或类都应该提到。其中一些可以用于列格式设置。
