There is also the 'Table and Chairs' PIO tool located in the 'Furn./Fixtures' tool palette, you can make the table any width / length that you want. But I don't think you can have chairs on only one side, so you'd have to put the chairs in manually. Create the Table, add the three chairs, select all four elements and create a 2D/3D Symbol.
On a side note, it is hard to believe that searching the Vw2015 & Vw2016 online help for 'table' doesn't return the 'Table and Chairs' tool in the results. It should be the first result.
