问题如题，代码如下，但是下面的代码在页面中并不是50% 大概每个formItem占了25%

         
            <Form :model="libraryInfo" :label-width="100">
              <Row>
               <Col span="12">
               <FormItem label="库位名称">
                <Input v-model="libraryInfo.libraryName"></Input>
               </FormItem>
               </Col>
               <Col span="12">
               <FormItem label="条码号">
                <Input v-model="libraryInfo.simpleCode"></Input>
               </FormItem>
               </Col>
              </Row>
            </Form>
