表格列的定义，结构为
<pre>interface GridColumnDefinition {
key?: string;
type?: keyof GridColumnType | typeof GridColumn;
caption?: string;
width?: Number;
align?: "left" | "center" | "right";
enabled?: boolean | string;
css?: { [key: string]: string };
styleFilter?: (item: GridItem | any) => { [key: string]: string };
textStyle?: { [key: string]: string };
visible?: boolean;
resizable?: boolean;
sortable?: boolean;
orderable?: boolean;
allcheck?: boolean;
events?: { [event: string]: any };
attrs?: { [key: string]: string } | ((item: GridItem | any) => { [key: string]: string });
filter?: (item: GridItem | any) => any;
sortFilter?: (a: GridItem | any, b: GridItem | any) => -1 | 0 | 1;
bgFilter?: (item: GridItem | any) => string;
dropOptions?: DropdownOptions;
source?: Array<any> | ((item: GridItem | any) => Array<any> | Promise<Array<GridSourceItem>>);
iconType?: string;
text?: string;
tooltip?: string;
onallchecked?: (this: Grid, col: GridColumnDefinition, flag: boolean) => void;
onchanged?: (this: Grid, item: GridItem | any, value: boolean | any) => void;
}</pre>
</p>
<h3>key</h3>
<code>key?: string</code>
<p>关键字</p>
<h3>type</h3>
<code>type?: keyof GridColumnType | typeof GridColumn</code>
<p>列类型，可以为 <code>Grid.ColumnTypes</code> 枚举值表示内置的通用、输入、下拉、复选框、图标等类型
<pre>declare var ColumnTypes: {
Common: 0,
Input: 1,
Dropdown: 2,
Checkbox: 3,
Icon: 4,
isCheckbox(type: Number): boolean;
}</pre>也可以为符合 <code>GridColumn</code> 接口的类或对象表示自定义类型，接口定义如下
<pre>interface GridColumn {
static create(): HTMLElement;
static createEdit(trigger: (e: any) => void, col: GridColumnDefinition, body: HTMLElement): HTMLElement;
static setValue(element: HTMLElement, val: any): void;
static getValue(e: any): any;
static setStyle(element: HTMLElement, style: { [key: string]: string }): void;
static setEnabled(element: HTMLElement, enabled?: boolean): void;
}</pre>
</p>
<h4>create</h4>
<code>static create(): HTMLElement</code>
<p>创建只读状态的单元格元素</p>
<h4>createEdit</h4>
<code>static createEdit(trigger: (e: any) => void, col: GridColumnDefinition, body: HTMLElement): HTMLElement</code>
<p>创建编辑状态的单元格元素</p>
<samp>trigger: (e: any) => void</samp>
<p>用以触发 Grid 的列修改事件 <code>columnChanged</code> 的函数代理</p>
<samp>col: GridColumnDefinition</samp>
<p>当前列的定义对象</p>
<samp>body: HTMLElement</samp>
<p>Grid 正文表格元素</p>
<h4>setValue</h4>
<code>static setValue(element: HTMLElement, val: any, item: GridItem | any, col: GridColumnDefinition): void</code>
<p>设置单元格值时触发的函数</p>
<samp>element: HTMLElement</samp>
<p>单元格元素</p>
<samp>val: any</samp>
<p>单元格的值</p>
<samp>item: GridItem | any</samp>
<p>单元格所在行的数据项</p>
<samp>col: GridColumnDefinition</samp>
<p>单元格所在列的定义对象</p>
