Please be aware that in the configurations below that due to the fact that you are reaching over/behind the 30 inch width of the outer tables, the center of the interior elevated table is not easily accessible.The configurations are really designed for displays in the center.( Large centerpieces and visual displays that do not need to be accessed by guests.) The configuration at bottom right allows for the best center table access because the tables are 18 inch narrows. The overlapping configurations such as the 60 inch round in the center of 48 inch serps offer increased accessibility.
