IMPORTANT!!!!!!! I need add text entry row and remove by button or automatically.

Hi there, if you still need, I was able to put this in place with a button by tweaking the code in this thread. Try creating a Form Field question and adding the below to the question's JavaScript in the OnReady section:
var that=this.questionId;
jQuery("#"+this.questionId+" tr:not(:eq(0))").hide();
jQuery("").insertAfter("#"+this.questionId+" tr:last");
jQuery("#add").on('click',function(){
        var c=jQuery("td.ControlContainer:visible").length;
        jQuery("#"+that+" tr:eq("+c+")").show(); 
    });
