Button: Cut row to next row, pushing all rows below.

    I'm gonna try to explain what I want to do :
    [A1]label1 [A2]lbl2 [A3]lbl3
    [B1]inputtext [B2]inputtxt [B3]checkbox [B4] Button - Insert
    
    I complete the inputs, press Insert and :
    [B1] cuts+pastes in [C1] , [B2]in [C2] etc;
    But, what was in [C1] will move to [D1], [D1]  to [E1] etc;

* Is this possible ? What should i learn to accomplish this ?
