ExtJS3.2 已经有了tableform布局(bug fix)
(最新修改：覆盖renderAll方法，使得hidden类型的控件不布局）

通过不懈的google，终于还是在Extjs上找到了tableform 布局的代码，这可以终结网上大部分通过hbox,或者column来布局form 的代码例子了。


   先看一个例子
  
var form = new Ext.form.FormPanel({
renderTo:'content',
layout:'tableform',
width:600,
frame:true,
title:'test',
layoutConfig: { columns: 2 },
                    items: [
                        { fieldLabel: 'Created By:', xtype: 'textfield'
                        },
                        { fieldLabel: 'Author:', xtype: 'textfield'
                        },
                      
                        { fieldLabel: 'Creation Date:', xtype: 'datefield' },
                        { fieldLabel: 'to', xtype: 'datefield' },
                        { fieldLabel: 'Modified By', xtype: 'textfield',colspan: 2},
                        { fieldLabel: 'Modified Date:', xtype: 'datefield' },
                        { fieldLabel: 'to', xtype: 'datefield' },
                    


})

   

tableform的好处是你可以一直增加表单还不用考虑布局。这个有点类似我8年前swing布局中写的一个布局管理器

            } else {
