An adjustable table is composed of a tabletop, a foot frame and a telescopic tube. The tabletop has a combining plate at the bottom. The frame consists of a sleeve, a movable ring, plural support legs and a fixing ring. The movable ring is fitted around the sleeve while the fixing ring is secured on the lower end of the sleeve. The support legs are respectively and pivotally connected with the movable and the fixing toggle, able to be simultaneously expanded outward to stand stably on the ground. The telescopic tube has its upper end assembled with the tabletop and its lower end inserted in the sleeve, having a connecting plate on top for assembling with the combining plate of the tabletop. The telescopic tube is able to move up and down for adjusting height of the tabletop.

What is claimed is:  
     
         1 . An adjustable table comprising: 
 a tabletop provided with a combining plate at the bottom;    a foot frame positioned under said table top, said foot frame composed of a sleeve, a movable ring, a plurality of support legs and a fixing ring, said movable ring fitted around said sleeve, said fixing ring secured on the lower end of said sleeve, said support legs respectively and pivotally connected with said movable ring and said fixing ring, said support legs able to be simultaneously expanded outward to stand stably on the ground;    a telescopic tube having its upper end connected with said table top and its lower end inserted in said sleeve, said telescopic tube fixed with a connecting plate on top, said connecting plate assembled with said combining plate of said table top; and,    said telescopic tube able to move up and down in said sleeve and adjust said table top to a suitable height, said adjustable table able to be assembled and disassembled fast and convenient to be collapsed.    
     
     
         2 . The adjustable table as claimed in  claim 1 , wherein said combining plate of said tabletop is provided with at least one engage groove.
