element picker-options控制时间只能选取指定范围日期

需求:

用户只能创建当前的月报,如果当年已有月份有了月报那么这个月也不可以建月报

 			<el-form-item label="月份：" :prop="isdisabled?'':'stateDate'">
              <el-date-picker
                v-model="ruleForm.stateDate"
                value-format="yyyy-MM"
                format="yyyy-MM"
                class="control"
                type="month"
                placeholder="选择月"
                :picker-options="pickerOptions"
              />
            </el-form-item>
			
			
			
		const pastMonthList = []
		const date = new Date()
        const curYear = date.getFullYear()
		if (params.year < curYear) {
            for (let i = 1; i <= 12; i++) {
              // 年份与月份拼成数组
              pastMonthList.push(`${params.year}-${i < 10 ? '0' + i : i}`)
            }
            this.creatDateList = pastMonthList.filter((m, idx) => {
              // 返回没有匹配上的日期,allMon为后台返回的月份
              return allMon.indexOf(m) === -1
            })
          } else {
            //currentMonth这当年及当月之前所有月份
            this.creatDateList = currentMonth().filter((m, idx) => {
              // 返回没有匹配上的日期
              return allMon.indexOf(m) === -1
            })
          }
		  
		  
		    pickerOptions: {
          disabledDate: (time) => {
            const year = time.getFullYear()
            let month = time.getMonth() + 1
            if (month < 10) month = '0' + month
            const ym = year + '-' + month
            // 把所有年月和需要建立的月份匹配,把没有匹配上的返回出去,让月份选择器可选
            return !this.creatDateList.includes(ym)
          }
        },

我实际项目中需求的是这个：
