ขอถามหน่อยครับ ถ้าผมจะเพิ่มหัวข้อเป็นแบบกรอกข้อมูลอีกชุดจะทำไงดีครับ

 function CreateNewRow()
    {
          var item1 = 0;
        var intLine = parseInt(document.form1.hdnMaxLine.value);
        intLine++;
            
			num++;
			
			
		
			
			
			
			
        var theTable = document.all.tbExp;
        var newRow = theTable.insertRow(theTable.rows.length);
        newRow.id = newRow.uniqueID;
        
    
        var newCell;
        var bark;
        //*** Column 1 
		
		
		
	
	count1 += 1; 
	
  
   
        newCell = newRow.insertCell(0);

        newCell.id = newCell.uniqueID;
        newCell.setAttribute("className", "textb11");
		
        newCell.innerHTML = "<tr><td class=\"textbB12\" ><div align=center><input type=\"TEXT\" SIZE=\"7\" NAME=\"item[]\" VALUE=\"\" class=\"textb11\" ID=\"item19"+intLine+"\" placeholder=\"แถวที่"+num+"\"></div></td>";

        //*** Column 2 ***//
        newCell = newRow.insertCell(1);
        newCell.id = newCell.uniqueID;
        newCell.setAttribute("className", "textb11");
        newCell.innerHTML = "<td class=\"textbB12\"><div align=center><input type=\"TEXT\" SIZE=\"69\" MAXLENGTH=\"45\" NAME=\"desc[]\" VALUE=\"\" class=\"textb11\" ID=\"desc19"+intLine+"\"></div></td><br>";     
        
        //*** Column 3 ***//
      
        document.form1.hdnMaxLine.value = intLine;
		
		
    
    }
