解决el-table表格拖拽后,只改变了数据,表头没变的问题-CSDN博客
限制拖拽
sortableJs有个配置项是filter,过滤掉不可进行拖拽的列或行。
本文采用vue3+ele-plus的table组件结合sortableJs插件对表格拖拽需求进行开发:
列拖拽:
使用:header-cell-class-name="headerCellClassName"对el-table的列增加headerClassFilter类名,有此类名的行不可进行拖拽(在Sortable.create实例中对headerClassFilter类名进行过滤,即filter绑定的类名)。
- <template>
- <div>
- <el-table
- :data="tableData"
- border
- scrollbar-always-on
- ref="tableHeader"
- row-key="id"
- :header-cell-class-name="headerCellClassName"
- >
- <template v-for="item in setColumns" :key="item.label">
- <!-- 操作列 -->
- <el-table-column
- v-if="item.prop === 'oprate'"
- fixed="right"
- :prop="item.prop"
- :label="item.label"
- >
- <template #header>
- <div class="search-title">
- <div :class="checked ? 'search-titleName' : ''">操作</div>
- <el-icon class="search-icon" @click="search">
- <Search color="#409EFF" />
- </el-icon>
- </div>
- </template>
- </el-table-column>
- <!-- 序号列 -->
- <el-table-column
- v-else-if="item.prop === 'index'"
- :type="item.type"
- :label="item.label"
- :width="item.width || 100"
- />
- <!-- 数据列 -->
- <el-table-column
- v-else
- :prop="item.prop"
- :label="item.label"
- :width="item.width || 100"
- />
- </template>
- </el-table>
- </div>
- </template>

- <script setup lang='js'>

行拖拽:
使用:row-class-name="rowClassName"对el-table的行增加rowClassFilter类名,有此类名的行不可进行拖拽(在Sortable.create实例中对rowClassFilter类名进行过滤,即filter绑定的类名)。
