A "frequency table" just refers to a kind of table you can make to record the frequency of particular results or events, as part of an experiment or to analyse data. It is convenient to list the possible events or results along the left side of the table, and then make tally marks across from them, in order to count the number of times each one appears; thus, the tally marks represent each event or result's frequency, or the number of times it shows up.
The tally marks I'm familiar with cannot have negative numbers because they are used to count real things and there cannot be a negative apple
