A table arrangement including a support member rotatably mounted to a base structure, a table element translatably mounted to the support member, and a locking mechanism is described. The locking mechanism may include a first locking member connected to the support member to rotate with the support member between non-aligned and aligned configurations with respect to the second locking member, and a second locking member. The first or second locking member may be translatably mounted with respect to the other locking member between a first engagement position and a second engagement position, wherein, when the first locking member is in the aligned configuration, the first or second locking member can translate into the second engagement position. The table arrangement may be deployed and stowed.
