Erase / Filter rows with info from the ones in blank

Question

I have this data in a Google Sheet, basically is a dynamic table that will have more information or could change in a future with more or less rows, in the same image at the right you will see what I need, I was thinking about use BLANK but is giving me some errors, also I tried with transposeFilter but same problem. Some help or recommendations please! (The only information not dynamic is the blue rows)

Answer 1

try for horizontal erase:

=FILTER(A:D; TRIM(FLATTEN(QUERY(TRANSPOSE(A:D);;9^9)))<>"")

or vertical erase:

=FILTER(A:D; TRIM(QUERY(A:D;;9^9))<>"")
