I claim the ornamental design for a dining table, as shown and described.
FIG. 1 is a perspective view of my new design;
FIG. 2 is a right side view thereof;
FIG. 3 is a front view thereof;
FIG. 4 is a top view thereof; and,
FIG. 5 is detailed view of a leg portion of the dining table.
The bracketed dash-dot lines in FIGS. 1-4 represent boundaries that form no part of the claimed design such that the area between the dashed-dot lines forms no part of the claimed design. The dash-dash lines in FIG. 1 represent environmental portions that form no part of the claimed design. The wavy dash-dash line in FIG. 5 represents an end of the detailed portion that forms no part of the claimed design.
The outer surfaces of the legs are characterized by a rough surface pattern with horizontal striations.
