depends how the building is designed
how big it is
how cheaply its been built/designed
having wide open spaces costs lots of money
having lots of pillars is cheaper to build
a small floor area may be capable of being supoorted by a skeleton that is buried in the outside walls. as the floor sapce becomes wider that skeleton becomes prohibitively expensive, the mor efloors you add the more load you add the more support you need.
sometimes pillars are put in to run services (electricity, data cables, water etc......), or if its to provide a local support for soundproofing or door frame etc..... but usually a pillar is there for structural reasons its holdign the floor(s) above up.

The question you asked pertains to the civil engineering design which deals with structures etc. The Pillars are primarly there to bear the load of the cealing but the current development of civil engineering design and RCC techique has made it possible to minimise the pillars to the maximum extent that is why based on the design some buildings have more pillars and some may have none. Regarding decoration , naturally when you place pillars in between you try to make them decorative so that the building would look more presentable.

It's just alternative methods of Construction. Basically the larger the building the larger the internal "spans" of each floor. Depending on the purpose of the building the "loadings" will change e.g. - Car Park will support 1.5ton 4x4's and occupants/luggage parked 1meter apart and Art Gallery - Couple of paintings/artwork and 20 folk on walkabout - so car park needs more supports. Also cost issue - when Indoor Stadium needs open space with no supports span gets bigger cost goes up. Archive storage building - costs important - sacrifice open span for pillars - costs go down....

it depends how big the buildings are etc or how much weight is on the ceiling! they are load bearing as the walls cannot take all the weight!
