1. A patient support apparatus comprising: a frame;a deck supported by the frame; anda siderail comprising a table portion movable between a table position in which the table portion extends generally horizontally over at least a portion of the deck and is spaced from the deck, and a siderail position in which the table portion extends generally vertically along at least a portion of a side of the deck. 2. The patient support apparatus of claim 1, comprising a main siderail portion and a hinge rotatably connecting the table portion to the main siderail portion. 3. The patient support apparatus of claim 2 wherein the table portion and the main siderail portion both extend generally vertically along at least the portion of the side of the deck when the table portion is in the siderail position. 4. The patient support apparatus of claim 1, wherein the siderail is movable from a deployed position in which a majority of the siderail is higher than the deck and a stored position in which a majority of the siderail is lower than the deck. 5. The patient support apparatus of claim 4 further comprising a latch for latching the siderail in the deployed position. 6. The patient support apparatus of claim 1 in which the table portion of the siderail is an extension portion. 7. The patient support apparatus of claim 2 in which the main siderail portion of the siderail is a heel and the table portion of the siderail is an extension. 8. The patient support apparatus of claim 7 wherein the frame includes a mechanism connected to the siderail enabling the siderail to be raised and lowered relative to the deck, and wherein the heel is connected to the mechanism and is pivotable about a heel axis relative to the mechanism, and wherein the extension extends from the heel and is pivotable relative thereto about a drop axis. 9. The patient support apparatus of claim 8 wherein with the table portion of the siderail in the siderail position: a) the heel and extension are substantially coplanar with each other such that the siderail extends predominantly in the longitudinal and vertical directions and borders a lateral side of the deck;b) the heel axis extends substantially laterally;c) the drop axis extends substantially vertically;and wherein with the table portion of the siderail in the table position:a) the heel borders the lateral side of the deck;b) the heel extends predominantly in the longitudinal and vertical directions;c) the extension extends predominantly in the longitudinal and lateral directions;d) the heel axis extends substantially laterally; ande) the drop axis extends substantially longitudinally. 10. The patient support apparatus of claim 7 wherein with the table portion in the table position the extension defines a substantially horizontal table having a first dimension and a second dimension substantially orthogonal to the first dimension. 11. The patient support apparatus of claim 10 wherein the hinge defines a drop axis and the extension is pivotable relative to the heel about a swing axis which is substantially perpendicular to the drop axis. 12. The patient support apparatus of claim 11 wherein the extension is pivotable relative to the heel between a first table position in which the first dimension extends in the longitudinal direction and the second dimension extends in the lateral direction, and a second table position in which the table is still horizontal and the first dimension extends laterally and the second dimension extends longitudinally. 13. The patient support apparatus of claim 12 wherein the second table position is a position substantially laterally outboard of the deck. 14. The patient support apparatus of claim 7 wherein the heel and extension have mutually proximate edges and the extension is pivotable relative to the heel about a drop axis substantially parallel to the mutually proximate edges. 15. The patient support apparatus of claim 14 wherein the extension is pivotable relative to the heel about a swing axis perpendicular to the drop axis. 16. The patient support apparatus of claim 8 wherein only when the table portion is in the table position the extension is also pivotable relative to the heel about a swing axis perpendicular to the drop axis. 17. The patient support apparatus of claim 7 comprising: a curved rail projecting from an underside of the extension; anda guide slot in the heel, the guide slot and the rail being engageable with each other only when the extension and the heel are oriented substantially perpendicular to each other. 18. The patient support apparatus of claim 17 wherein engagement of the rail and the guide slot prevents upward rotation of the extension about the hinge. 19. The patient support apparatus of claim 18 in which the hinge defines a drop axis, the rail includes a foot, and the slot includes an overhang, and in which the rail foot cooperates with the overhang to prevents upward rotation of the extension about the drop axis. 20. The patient support apparatus of claim 7 in which the table portion is positionable in a position intermediate the siderail position and the table position, the intermediate position being one in which the heel and extension are substantially coplanar with each other, a heel axis extends substantially laterally and a drop axis extends substantially longitudinally. 21. The patient support apparatus of claim 20 wherein when the table portion is in the intermediate position and the extension and the heel are in a coplanar relative orientation, the extension is rotatable about the drop axis but not about a swing axis.
