The broken lines shown in the drawings represent portions of the end table that form no part of the claimed design. The dot-dashed lines in the figures represent boundary lines defining a boundary of certain aspects of the claimed design. It is to be understood that the claimed design extends to but does not include the defined boundary. For instance, dot-dashed lines are used in the figures to, inter alia, define a boundary of or within the body of the end table, it being understood that the claimed design extends to but does not include the boundary.
