How to read this table
The bolded horizontal headings stand for the main condition that affects the following slots; the big cells on the left side describe which circumstances must apply for the rows they span to be active. The percentages tell you the chance of a Pokémon from this slot (row) appearing for any given wild encounter, provided the condition on the left holds.
Each condition (i.e. each bolded horizontal heading) always has the same number of slots active. Usually it's two, though the radio condition in HG/SS has four slots and tables can have any number of static slots combined under one blank condition (-) for less cluttered viewing. This is reflected in the slots usually being displayed in pairs, which except for the aforementioned HG/SS radio conditions always means that only one pair is active at any one time. (For the radio conditions, it's either two pairs or one quadruple.)
If all this confuses you, and I don't blame you, just set the conditions in the form on the right to what actually applies for you right now and press the Refresh Table View button, which will hide all the inactive slots and leave only the Pokémon you're actually going to be seeing. This will also recalculate the statistics at the bottom of the table accordingly.
Note that HG/SS swarms are a bit wonky at the moment; a bunch of ordinary, common Pokémon are listed as swarming in various locations. This is an error and will be fixed as soon as Eevee updates his database. Before that happens, however, just ignore all supposed "swarms" of Pokémon that are already listed in one of the first two slots when it's not swarming; they don't actually happen.
