We refer to the basic forces of repulsion to explain that. I don't remember which one it is. (the electric force maybe?). -snickersnack

err, not the best example, you're probably right, that the E-M force (u said u didnt know which force it is, it is the E-M force) explains this.
i should have said it this way instead:
the E-M force explains how the table can be and is solid ("hard") despite that it's made up of atoms that are 99% empty space or nothing. but, it doesn't explain why or how we see the table, why don't we see the 99% empty space that it is made of, why do we see a table when there is no table, it's just empty space. how is there a visible table from empty space?
------------------------------------------------------------------------------------
explanation of how the E-M force makes the table solid ("hard"):
background info:
big bang:
1 super force originally. it than for some reason, broke into the 4 forces and through inflation was exploded out...giving us what we understand as the universe.
the 4 forces that we are so familiar with (at least those who know-interested in science or science career-job-classes):
strong force (nuclear force. it holds the protons and neutrons together making the nucleus possible. it's this force's bonds that are broken and re-connected that gives us nuclear energy either for a plant or a weapon-bomb).
(well the neutrons might be held together by the gluon's? Rather than by the strong force but that's getting into too much detail. i can't remember if gluon's is right or not if that what the gluon's do, holding the neutrons together or something else. gluon's, mesons, neutrinos, and etc are the other sub-atomic particles. protons, neutrons, and electrons aren't the only sub atomic particles)
weak force (radioactive decay. the "destroyer" force. breaks down uranium into lead. it's like the backward force of sun-solar fusion, undoing what stars-suns do with fusion)
gravity force: (pull or inward or attraction force. the puny-EST and weakest force but at the macro scale it is the force that controls the universe and all macro physics like black holes, the red shift, big bang, universe, stars, falling on your rear lol, etc etc.
E-M force (electro-magnetism force. "opposites attract". "+" charge and "-" charge attraction and "maybe" male and female attraction. explains static electricity when u shock people even still as an adult *grins* i can't grow out of it! and why your hair stands up or why water coming out your sink facet will bend to your charged hair comb and etc..)
(scientists are so imaginary EXCEPT with names! electricity and magnetism are the SAME thing, and creatively (sarcasm) scientists have named this now old discovery electro-magnetism. its the same lack of creativity with space-time and matter-energy. Einstein with his E=MC^2 showed us that matter and energy are the same thing and with his time dilation showed us that space and time are the same thing, space-time, so creative (sarcasm).
anyways finally about E-M: it is also what keeps electrons whizzing around the nucleus of an atom
and long last:
it's theorized that the POWERFUL E-M force that creates a "magical" bond between the nucleus and the electrons whizzing around, is what keeps a person or car or meteor "falling" from a cliff or building or space due to puny weak force of gravity, from "falling" right through the entire earth or ground and out the other side of the planet earth.
this theory also explains why the table is solid ("hard") despite being made up of 99% empty space or nothing.
gravity is very very weak compared to the 3 other forces, but people get confused because they only see gravity on a massive scale and understandably think it is a powerful force when it really isn't. i don't wanna imagine the other 3 forces at the same scale as gravity is, in fact, the universe/existence would NOT be possible if the 3 other forces reached the same scale as gravity can and is at.
