如何做一个两列的FormPanel

有时一个FormPanel 放很多输入框会变的很长，这时候需要分成两列比较美观，下面就是代码了  

 

//add buyer form panel.
  var formPanel = new Ext.FormPanel({
         frame: true,
         labelAlign: 'right',
         labelWidth: 85,
         width:450,
         waitMsgTarget: true,
         items: [
          {layout:'column',width:450,items:[
           {layout:'form',columnWidth:.50,items:[
                  buyerId,
               buyerName,
            buyerAgent,
            buyerCommission,
                  buyerBank,
                  buyerAccount,
                  buyerPostcode
           ]},
           {layout:'form',columnWidth:.50,items:[
            buyerTaxnum,
                  buyerTele,
                  buyerEmail,
                  buyerAddr,
                  buyerFlag,
                  buyerSpell
           ]}
 
          ]}
         ]
     });
