el-table toggleRowSelection被动触发select/selection-change事件的解决方案

场景：接口返回的数据需要列表默认选中，需要调用toggleRowSelection方法，但由于非当前页数据不在数据项内，toggleRowSelection默认触发select事件导致多选数组非当前页数据被干掉

解决方案：加锁

rowSelectFlag: false // 禁止toggleRowSelection默认触发handleSelectionChange

handleSelectionChange(val) {
    if (this.rowSelectFlag) return
    this.multipleList = val
},
        
setRowSelected() {
    setTimeout(() => {
         this.rowSelectFlag = true
         this.dataList.forEach(row => {
            const matchedIndex = this.multipleList .findIndex(item => item.id === row.id)
            this.$refs['modal_table'].toggleRowSelection(row, matchedIndex != -1)
        })
        this.rowSelectFlag = false
    }, 0)
},
