Is it possible making spike lines in several subplots having 2 columns?

I’m making a graph with 3 rows and 2 columns. (refer to below figure)

Is there any method applying vertical spike line sharing x-axis in all subplots?
(all subplots share the x-axis.)

Hi @kormo09 and welcome to the community!

Have you looked through the solutions/discussion from the below threads with a similar topic?

Thank you for your kind reply.
But the links in your answer correspond to multiple plots with only 1 column.
My question is about more than 2 columns.
