VTABLE 基本表和透视表的分页功能

基本表和VTable数据分析透视表支持分页，但透视组合图不支持分页。
配置项：

  • pagination.totalCount：数据项的总数。数据透视表中的VTable字段将被自动补充，以帮助用户获取数据项的总数。
  • pagination.perPageCount：显示每页的数据项数。注意!数据透视表中的perPageCount将自动更正为指示器数量的整数倍。
  • pagination.currentPage：当前页码。

方法：Methods.updatePagination，更新页码配置信息，调用后会自动重绘。

 /*** Update page number* @param pagination The information of the page number to be modified*/updatePagination(pagination: IPagination): void;

IPagination type define:

/***Paging configuration*/
export interface IPagination {/** The total number of data, this data in the pivot table will be automatically added without user input */totalCount?: number;/** Display number of data items per page */perPageCount: number;/** Display number of items per page */currentPage?: number;
}

使用：

const tableInstance = shallowRef();
tableInstance.value = new ListTable(listTableRef.value, option);
tableInstance.value.updatePagination({
perPageCount: number;currentPage: pageNumber});

基本表（ListTable）的分页

基于百万级数据的秒级渲染的demo做的分页， https://visactor.io/vtable/demo/performance/100W
分页html相关代码：

<div style="width: 1580px; height: 50px" class="right-align"><button id="first-buttom" > 首页</button><button id="prev-buttom" > 上一页</button><span id="page-namber">第1页</span><input id="cpnr" type="hidden"><span>/</span><span id="total-page">共 页</span><input id="mpnr" type="hidden"><button id="next-buttom">下一页</button><button id="tail-buttom" > 尾页</button><span id="total-num">共 条</span><input  id="spn" type="number" ><button id="skip-buttom"> 跳转</button></div>
