Questions about the usage of

I have 10 elements in my list. How to use <logic: iterator> to display these 10 elements in two lines (or 3 lines, etc.)?

Has anyone done this before?
I have used the most stupid method, split into two LIST, is there a direct way?

<logic:iterator>
<tr><td><bean:write /></td></tr>
</logic:iterator>
is this okay?

Use Struts logic tags, use indeId to automatically output the serial number and add one when traversing the List
  Examples are as follows:
   
  <table>
  <tr>
  <td>Serial number</td>
  <td>Name</td>
  ...
  </tr>
  <logic:present name="targetbean">
  <logic:iterate name='helperbean' id='helperbean' type='net.echochina.HelperBean' scope='request' indexId="index">
  <tr>
  <td><%= index.intValue() + 1 %></td>
  <td><bean:write name='helperbean' property='name' /></td>
  .....
  </tr>
  </logic:iterate>
  </logic:present>
  </table>

Deal with index.intValue() /2 or /3 yourself, and organize <tr><td>.

Positive answer upstairs
In <logic:iterate> you can <bean:write name="index"/> to get the current record position (starting from 0)

Let me talk about the solution. If only one column is displayed when traversing, then a List is passed from the background, but if you want to display two columns, then put a List to put information into two Lists through a for loop. Go to the front desk to traverse in two columns, it's very simple

<logic:iterate name='aaaaa' id='bbbbbb' indexId= "index ">
    <tr>
    <td> <bean:write name ='aaaaa' property ='name' /> </td>
    .....
    </tr>
</logic>
Note: Generally iterate is used to indicate the details. The corresponding ACTIONFORM is generally List<Object>. The indexId is used to identify the row when performing JS operations on the details. Refer to the 6th floor for specific usage. The difficulty lies in the details. In the case of input, the back-end actionform needs special processing.The specific method can be checked on the Internet.In addition to the definition of List<Object>, it is also necessary to define the Object in List<Object>, the name is the same as name ='aaaaa'.
