Ask HN: It would be nice if text editors and IDEs would show the tab number

It may be a feature but I cannot find it. The two main applications I am using is Visual Studio Code and Jetbrains IDEs.

In both, I can see what line number and column my cursor is located. This is incredibly useful when I need it.

What I cannot see is the tab number where my cursor is.

This is probably a niche request but I am double checking and validating tab separated text files and the only way I can verify it is in the correct column is counting from the left.

Visual Studio Code at least has an extension that color codes the columns so that makes it somewhat easier with CSV files.
