// Array data for the grids

    ['Altria Group Inc',83.81,0.28,0.34,'9/1 12:00am', 'Manufacturing'],
    ['American Express Company',52.55,0.01,0.02,'9/1 12:00am', 'Finance'],
    ['American International Group, Inc.',64.13,0.31,0.49,'9/1 12:00am', 'Services'],
    ['AT&T Inc.',31.61,-0.48,-1.54,'9/1 12:00am', 'Services'],
    ['Boeing Co.',75.43,0.53,0.71,'9/1 12:00am', 'Manufacturing']
];

说明：1，x-grid3-row-alt {
                    background-image:none;
                    background-color:#F4FAFF;
            }

         此代码是设置斑马线行颜色。

         2，css : 'background: #FF0000;'

          此代码是设置列颜色。

        3，var cell=grid4.getSelectionModel().getSelections();
             if(btn=="yes"){
                  for(var i=0;i<cell.length;i++){
                      cell[i].set('company',i);       // 修改company的值
                      cell[i].commit();
                  }
            }

           此代码是实现值修改。

        4， var store=grid4.getStore();     // 删除选中的行
                 for(var i=0;i<cell.length;i++){
                       store.remove(cell[i])
                 }

            此代码是实现删除选中的行。
