A table apparatus includes a first driver applying force in a first axis direction to a table, and a second driver applying force in a second axis direction to the table. The first driver includes a first actuator generating power for moving the table in the first axis direction, and a first movable member moving along a first drive axis parallel to the first axis by actuation of the first actuator. The first movable member includes: a first linear bearing moving along the first drive axis; a first rotary bearing disposed around a first rod member fixed to the first linear bearing and rotatable relative to the first rod member; and a second linear bearing connected to the first rotary bearing and guided in the second axis direction by a second guide member fixed to an edge of the table in the first axis direction.
