js中动态生成表格
function createTable() {
 var t = document.getElementById("myT");
 for ( var i = 0; i < 3; i++) {
  var r = t.insertRow();
  for ( var j = 0; j < 2; j++) {
   var c = r.insertCell();
   if (j == 0) {
    c.innerHTML = "姓名："+i+","+j;
   } else {
    c.innerHTML = "<input type='text' name='n' />";
   }
  }
 }
 t.setAttribute('border', '1');
}

function deleteTable() {

 var objTable = document.getElementById("myT");
 objTable.setAttribute('border', '0');
 for ( var i = 0; i <= objTable.rows.length+1; i++) {
  objTable.deleteRow(0);

 }
 
}

jsp中的表单引发事件
<input type="button" onclick="createTable()" name="ty" value="试题类型" />
   &nbsp;
   <input type="button" onclick="deleteTable()" name="re" value="清除表格" />
   <table id="myT">
