@DennisMB welcome to the KNIME forum. I have prepared this example on the KNIME hub. You can write a column expression testing a single column for your conditions (0 = a negative condition is met, 1 = the positive condition is met, 2= something else, maybe also a 1?)
Then for the fun of it I have built a system where you could apply the rules to all columns (you want). If we have one negative in a set of columns it is a negative overall and we would need at least one positive mark in all the columns. Other combinations are of course also possible.
The Multi Column node would allow for a combination of several conditions to be applied (true= keep it, false = drop it if a negative condition).
