[[“ A”，“ B”，“ C”，“ D”，“ E”，“ F”]-ArrayList 01
[[1,2,3,4,5,6]-ArrayList 02
[[10,20,30,40,50,60]-ArrayList 03
[100,200,300,400,500,600]-ArrayList 04
Main_List-[[“ A”，“ B”，“ C”，“ D”，“ E”，“ F”]，[1,2,3,4,5,6]，[10,20,30,40， 50,60]，[100,200,300,400,500,600]];
如何将Main_List检索到具有四列的表中？
<c:forEach items="${List_parameter}" var="post" varStatus="theCount">
<tbody>
<c:forEach items="${post}" var="value" varStatus="cell">
<tr>
<td scope="row">${theCount.count}</td>
<td>${value.get(0)}</td>
<td>${value.get(1)}</td>
<td>${value.get(2)}</td>
<td>${value.get(3)}</td>
<td>-</td>
</tr>
</c:forEach>
</tbody>
</c:forEach>
1）使用评估EL
2）创建列表并添加。
3）设置pageContext.setAttribute（“ list”，finalList）;
