It's strange to add data to the notepad and use t to split it. why is the length of each tab key inconsistent? Inconsistent?

It's strange to add data to the notepad and use t to split it. why is the length of each tab key inconsistent? Inconsistent? It's strange to add data to the notepad and use \ t to split it. The result is displayed in the notepad. are the tabs of different lengths different?

This is a problem with notepad. you can use notepad ++ or another editor to open a text file.

This is related to the number of spaces equal to tab. Notepad looks like 8.
