In a table, how can I select to display only certain columns and not others.

I have a table with around 60 columns. The number of columns will continue to grow. When I input data, I only need to work on a relatively small number of columns (say 6 columns), which could be located anywhere amongst the 60+ columns. For example, I might need to work on columns A,B,C and on columns BA, BB, BC at the same time.

This is becoming difficult to manage as I can't display the whole table on a single monitor, and I keep having to scroll huge distances to the left or right.

I have illustrated what I would like to achieve in the attached simplified spreadsheet.

I can achieve the required outcome by MANUALLY hiding or shrinking non-needed columns, but this is very tedious and time consuming - at least doing it manually. I would like to find a simpler way, I am sure someone here can help?

Below is a simple version of the spreadsheet.
