dhtmlx กับความส่งสัยของ Soul ตอนนี้ผมสามารถที่จะadd ข้อมูลโดยผ่าน grid ได้แล้ว แต่มีข้อสงสัย

<script>
	//init grid and set its parameters (this part as always)
	mygrid = new dhtmlXGridObject('gridbox');
	mygrid.setImagePath("../../codebase/imgs/");
	mygrid.setHeader("img:[../../icon/16x16/delicious.png]&nbsp; No,img:[../../icon/16x16/edit.png]&nbsp;MarkerName, img:[../../icon/16x16/issue.png]&nbsp;Plant,img:[../../icon/16x16/collaboration.png]&nbsp; Chr,img:[../../icon/16x16/milestone.png]&nbsp;Prosition, Trait,Markertype,Annealing_temp,Primer Sequence");
	mygrid.setInitWidths("50,150,150,80,150,80,80,120,200")
	mygrid.setColumnIds("No,MarkerName,Plant,Chr,Prosition,Trait,Mardertype,Annealin_temp,Primer_Sequence")
	mygrid.setColAlign("center,left,left,center,center,center,right,center,center")
	mygrid.setColTypes("dyn,ed,ed,ed,ed,ed,ed,ed,ed");
	mygrid.setSkin("dhx_skyblue");
	mygrid.setColSorting("int,str,str,str,str,str,str,str,str")
	mygrid.init();
