Every time I see a "periodic table of X elements" a question pops to my mind: what is the benefit of arranging elements totally unrelated to the natural ones using the same structure?

In the original table, elements are arranged in rows, columns and colors using their specific properties, which actually are not at all present in these html elements.

In this table I see only the meaning for the colors, but why not to use the two dimensions of the table to convey something different (losing, of course, the familiar shape)?
