結(jié)合v-for，el-row與el-col控制卡片的布局問題

使用element-ui提供的組件card展示商品，前端獲得所有商品后再card外用v-for循環(huán)輸出展示所有商品。
想要一行展示四個商品，但是不知道怎么控制el-row，與el-col，最后的到的效果每行之間沒有間隙，并且感覺其實所有商品還是在一行顯示，只是因為width不夠所以換行顯示，怎么解決以上問題？
1.代碼如下

            <el-row>
                <el-col :span="4" v-for="project in allprojects" :key="project.pid" :offset="1">
                    <el-card :body-style="{ padding: '0px', height:'360px'}" shadow="hover" style="width: 260px;height: 320px;">
                        <div style="padding: 6px;height: 310px;">
                            <div>
                                <div><font size="5">{{project.pcname}}</font></div>
                                <div style="position: relative;top: 15px;text-align: center;">{{project.pname}}</div>
                            </div>
                            <div style="position: relative;top: 30px;">
                                <img src="../images/project/prohead.jpg" class="image">
                                <div style="position: relative;top: 10px;left: 66px;"><i class="el-icon-time"></i>{{project.pdatesave}}</div>
                            </div>
                            <div style="position: relative;top: 45px;">
                                &nbsp;&nbsp;<i class="el-icon-view"></i><span>{{project.ppageview}}</span>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
                                <el-button type="text"><font size="4">查看</font></el-button>
                            </div>
                        </div>
                    </el-card>
                </el-col>
            </el-row>

注意事項：
這是為了圖方便才直接在el-col上直接寫的style，還可以通過CSS選中.el-col來添加相應(yīng)樣式
