el-tabel数据结构
此处为this.rolePermitItemList

合并后的样式：

el-table-column 需要添加property字段，属性值同props，用来判断需要合并的字段

<el-table :data="rolePermitItemList" style="width: calc(100% );margin-top:10px; "max-height="550" border ref="tableBoxTwo" :span-method="arraySpanMethod"><el-table-column :label="item.name" v-for="(item) in tableFieldTwo" :key="item.value":width="item.width" :align="item.align" :property="item.value"><template slot="header"><div><span class="name">{{ item.name }}</span><span class="unit">{{ item.unit ? '(' + item.unit + ')' : '' }}</span></div></template><template slot-scope="scope"><span style="font-size: 14px;font-family: MicrosoftYaHei;color: #4D4C4F;">{{scope.row[item.value]|| '-'}}</span></template></el-table-column><el-table-column align="left" :property="'peizhi'"><template slot="header"><div style="display: flex;align-items: center;justify-content: center;"><span class="name">权限</span></div></template><template slot-scope="scope"><div class="flex-row-nowrap flex-justify-space-around"><el-checkbox v-model="scope.row.checked"@change="checkboxChange(scope.row, 'two')" :data-a="responsive">{{scope.row.operateName }}</el-checkbox></div></template></el-table-column></el-table>
