table
丌 is a rare kanji that represents a table or stand. Its meaning is limited to this physical object.
丌 is a pictograph of a table or stand, with the horizontal top representing the surface and the two vertical strokes representing the legs.
The horizontal line is the tabletop, and the two vertical lines are the legs. Together they form a simple table.
For キ, imagine a small table shaped like a key: key -> キ, and the table's legs look like the teeth of a key.
