import React, { Component } from 'react';
import Button from 'bee-button';
import Checkbox from 'bee-checkbox'
import Table from 'bee-table'
import multiSelect from "bee-table/build/lib/multiSelect";


import Modal from '../../src';

let MultiSelectTable = multiSelect(Table, Checkbox);


class Demo10 extends Component {
    constructor(props) {
        super(props);
        this.state = {
            showModal: false,
            data: [
                { a: "杨过", b: "男", c: 30, d: '内行', key: "2", _checked: true },
                { a: "令狐冲", b: "男", c: 41, d: '大侠', key: "1", _checked: true },
                { a: "郭靖", b: "男", c: 25, d: '大侠', key: "3", _checked: true }
            ]
        };

    }

//后端回调方法，用户的sortFun和Grid的有时有冲突，所以重新定义了一个sort，传给Table
    if (sortObj) {
      sortObj.originSortFun = sortObj.originSortFun
        ? sortObj.originSortFun
        : sortObj.sortFun;
      sortObj.sortFun = this.sortFun;
      this.sort = sortObj;
    }
    if (props.canSum) {
      ComplexTable = sum(ComplexTable);
    }
    //根据条件生成Grid
    ComplexTable = sort(Table, Icon);
    
    if (props.multiSelect !== false) {
      ComplexTable =   multiSelect(ComplexTable, Checkbox);
    }
    if(props.loadLazy){
      ComplexTable = bigData(ComplexTable);
    }
    if (props.draggable) {
      ComplexTable = dragColumn(ComplexTable);
    }

    ComplexTable = filterColumn(ComplexTable, Popover);
     this.ComplexTable = ComplexTable;
    
  }
