Thanks. I see your code and fix the problem.

Hi,
I am not sure why it doesn't work for you. You might need to write a
verys simple example that doesn't work and post that. On the other
hand, I am certain that I could not display 57 columns across my
screen (but I have a tiny laptop.) Are you sure you want 57 columns?
The code pasted below works for me. You might try separating your
calls to WIDGET_CONTROL by changing the event handling in one and the
data in another.

****START
PRO Table_Test_Button_Event, ev
WIDGET_CONTROL, ev.top, GET_UVALUE = info
if (ARRAY_EQUAL(info.dim, [3,5])) then begin
info.dim = [3,7]

endif else begin
info.dim = [3,5]
value = FINDGEN(3,5)
endelse
WIDGET_CONTROL, info.tableID, SET_VALUE = value, $
XSIZE = info.dim[0], YSIZE = info.dim[1]
WIDGET_CONTROL, ev.top, SET_UVALUE = info
END
PRO Table_Test
x = FINDGEN(3,5)
tlb = WIDGET_BASE(/COLUMN)
table = WIDGET_TABLE(tlb, value = x)

EVENT_PRO = "Table_Test_Button_Event")
WIDGET_CONTROL, tlb, $
SET_UVALUE = {TABLEID: table, BUTTONID: button, DIM: [3,5]}
WIDGET_CONTROL, tlb, /REALIZE
XMANAGER, "Table_Test", tlb
