Create an AutoCAD TABLE using autolisp

Here is an example of creating a TABLE entity using lisp. This example also creates some FIELDS using lisp.

This routine allows the user to select closed polylines, and it will create a TABLE with two columns. One containing the area, and the other containing the ObjectID. The last row totals up the area. You could easily adapt this to show the layer, color or any other property.

The TABLE is creating on the current tablestyle, so depending on the settings of your current tablestyle, you may have to adjust the sizing arguments in the (vla-addTable…) function in order for the table to look acceptable. These sizes used here work with the Standard tablestyle in a new empty drawing.

  ; create an empty list, set a counter variable, and
  ; set a reference to the current model space.

  ; prompt the user to select closed polylines
  (princ "\n Select closed polylines ")
  (if (setq sset (ssget '((0 . "POLYLINE,LWPOLYLINE")(-4 . "&")(70 . 1))))
    ; if a valid selection set was generated, then proceed.
    (progn
    
      ; for each closed polyline selected, grab the ObjectID and Area
      ; and store these values in a list.
      (repeat (setq cnt (sslength sset))
        (setq a (vlax-ename->vla-object (ssname sset i)))
