model

Ext.define('KitchenSink.model.Company', {    extend: 'KitchenSink.model.Base',    fields: [        {name: 'name'},        {name: 'price', type: 'float'},        {name: 'change', type: 'float'},        {name: 'pctChange', type: 'float'},        {name: 'lastChange', type: 'date',  dateFormat: 'n/j h:ia'},        {name: 'industry'},        {name: 'desc'},        // Trend begins with the cerrent price.

GridPanel的行选择模型（SelectionModel）
一般情况下，表格中是不会出现复选框的，而是进行的点击行选中，默认为多选（“MULTI”）
如何添加复选框

selType: "checkboxmodel",selModel: {    injectCheckbox: 0,    mode: "SIMPLE",     //"SINGLE"/"SIMPLE"/"MULTI"    checkOnly: true     //只能通过checkbox选择},

通过代码选择行

//选择行，并保持其他行的选择状态grid.getSelectionModel().select(records, true);//选择所有grid.getSelectionModel().selectAll();//根据row index选择grid.getSelectionModel().selectRange(startRow, endRow, true)

获取选中行

var records = grid.getSelectionModel().getSelection();

显示行号，一般情况下是不显示的

columns: [    { xtype: "rownumberer", text: "序号", width:40 },    { text: '姓名', dataIndex: 'name' },    {        text: '年龄', dataIndex: 'age', xtype: 'numbercolumn', format: '0',    },    { text: '电话', dataIndex: 'phone', editor: "textfield" }],

实现表格的列编辑
1、添加编辑插件（行编辑是RowEditing）

plugins: [    Ext.create('Ext.grid.plugin.CellEditing', {        clicksToEdit: 1    })],

2、为需要编辑的列指定编辑

columns: [    { xtype: "rownumberer", text: "序号", width:40 },    { text: '姓名', dataIndex: 'name' },    {        text: '年龄', dataIndex: 'age', xtype: 'numbercolumn', format: '0',        editor: {            xtype: "numberfield",            decimalPrecision: 0,            selectOnFocus: true        }    },    { text: '电话', dataIndex: 'phone', editor: "textfield" }

表格再被编辑后会自动出现小红角，如果要去掉小红角

grid.on('edit', function (editor, e) {    // commit the changes right after editing finished    e.record.commit();});

选中单元格的内容，一般情况下单元格的内容是不可以被选中的

viewConfig:{    stripeRows:true,//在表格中显示斑马线    enableTextSelection:true //可以复制单元格文字}

禁止头部菜单，为每个column定义menuDisabled

{header: 'Idno', dataIndex: 'idno', width:150,menuDisabled:true}
