先上代码，注意文中的红色字体

1. var form = new Ext.form.FormPanel({ 
2.                 autoHeight : true, 
3.                 id : 'reformId', 
4.                 frame:true, 
5.                 width : 400, 
6.                 border: false, 
7.                 height:300, 
8.                 labelWidth:60, 
9.                 items: [{ 
10.                     layout:'column', 
11.                     border:false, 
12.                     items: [{ 
13.                         layout:'form', 
14.                         border:false, 
15.                         columnWidth:.7, //在这里写columnWidth，注意位置
16.                         items:[{ 
17.                         xtype : 'textfield', 
18.                         fieldLabel: '学校名称', 
19.                         id:'_ent_name', 
20.                         readOnly:true, 
21.                         anchor:'100%', //在这里写anchor
22.                         name:'entName', 
23.                         allowBlank:false 
24.                         }] 
25.                     },{layout:'form', 
26.                         border:false, 
27.                         columnWidth:.3, 
28.                         items:[{ 
29.                         xtype:'button', 
30.                         text:'选择学校', 
31.                         name:'choiceEnt', 
32.                         anchor:'50%', 
33.                         listeners :{ 
34.                             click :function(){ 
35.                                 choiceTarget(); 
36.                             } 
37.                         } 
38.                         }] 
39.                     }]} 
40.                     ,{ 
41.                     layout:'column',items:[{ 
42.                     layout:'form', 
43.                     border:false, 
44.                     items:[accountGrid] 
45.                     },{ 
46.                         layout:'form', 
47.                         border:false, 
48.                         items:[{ 
49.                         xtype:'textarea', 
50.                         columnWidth:1, 
51.                         fieldLabel:'备注', 
52.                         msgTarget : 'under', 
53.                         width:300, 
54.                         height:80, 
55.                         name:'note', 
56.                         emptyText:'请填写相关备注信息'}] 
57.                     } 
58.                 ] 
59.                 }] 
60.             }); 

看到了吧，如果一行中同一列有多个对象，就要用到columnWidth和anchor了，大家要注意它俩的位置，否则是出不了效果的。
