Conditional Format with drop down menu

I have a spreadsheet that I would like to format based on the selection in column A from a drop down menu. I have been able to format lines 3-5 how I would like the line to appear once a selection has been made. But I would like to utilize the formulas for all the rows. My issue is that there are basically 3 different options of what a row could look like, how do i merge that so that each row can potentially look 3 ways depending on the dropdown.

Thanks in advance!

Not exactly. I want the formatting to basically apply to the whole sheet so that when I select k-1 or w/h from the drop down in column a of any row, it will look like either row 3, 4, or 5 depending on which one i select. Does that make sense? Right now I have the 3 rows formatted separately but I beleive I would need to combine them and then apply that to the whole sheet. Please let me know what you think.

Basically, if you look at worksheet "sample (2)", where rows 2, 4 and 6 have no are the columns that I would like formatted (crossed out in red with gray background). The formatting I want is different for each selection of the drop down which is what I'm having a hard time with.

At the end of the day, I would like to have a spreadsheet in which all the fields are populated and I can go into column A of each row, select 'w/h' from the drop down of that row and have the cells crossed out if I don't need that info for w/h. In the same row I want to be able to select "k-1" and have different cells crossed out b/c that info doesn't relate to k-1s.

Yes! that will work, it will just be a pain going through every column. But thanks so much!
