element ui el-table表头单独设置字体大小

 1.给el-table-column加上类名class-name

<el-table-column class-name="column" prop="program_name">     <template slot-scope="{row}"><span>{{ row.program_name }}</span></template> </el-table-column>

2.在css中设置字体大小

<style scoped lang="less"> ::v-deep .column {    .cell {     font-size: 18px;     } } </style>
