              label="值"
              align="center"
            >
              <template slot-scope="scope">                
                <img v-if="scope.row.value.indexOf('png' || 'jpg' || 'jpeg') != -1" :src="scope.row.value" style="height: 50px" />
                <span v-else>{{scope.row.value}}</span>
