 * 获取数据信息，只获取字段名与字段值
 * @memberof DataTable
 * @param  {object} [options] [description]
 * @param  {string} [options.type=all]    获取数据的规则
 * all：所有数据
 * current：当前行数据
 * focus：焦点行数据
 * select：选中行数据
 * change：发生改变的数据
 * @param  {array} [options.fields]    需要获取数据的字段名数组
 * @return {array}        获取到的数据信息
 * @example
 * datatable.getSimpleData() // 获取所有数据信息
 * datatable.getSimpleData({type:'current'}) // 获取当前行数据信息
 * datatable.getSimpleData({type:'current','fields':['filed1','field3']}) // 获取当前行field1和filed3数据信息
