How to make flex grid items stretch horizontally based on content?

Question

css

It is necessary to make stretch as if columnar depending on the column, but I don’t understand how to implement this in flex
Is it possible to do this only on table?
PS: Creating columns for elements is not a solution, the task is to make blocks with such a stretch that go in the same parent one after another
. Thank you very much!

Answer 2

I'm afraid that on the flex - no way. Either scripts, or grids, or (horror) a table.
