Teaching demonstration system and method for automatically updating simplex table

The invention provides a teaching demonstration system and method for automatically updating a simplex table. The system comprises a processor and a display which communicates with the processor, wherein the processor carries a first table; a to-be-demonstrated objective function and parameter data are obtained; the obtained target function and parameter data into a first table are inputted to obtain a coefficient matrix; the obtained coefficient matrix and the corresponding data are utilized to obtain a basis matrix table with at least one variable selectable and data; according to the obtained coefficient matrix, the basis matrix and the corresponding data, a simplex table and the corresponding data are obtained in a preset area of the first table, and the obtained simplex table and the corresponding data are displayed in real time through a displayer; according to the method, a linear programming problem of the user can be constructed according to requirements, modeling and calculation demonstration are ca
