easyexcel多级表头导出各级设置样式（继承HorizontalCellStyleStrategy实现）

  EasyExcel.write(response.getOutputStream(), ParamWorkdaysExportExcel.class)
    .registerWriteHandler(new CellStyleStrategy(new WriteCellStyle()))
    .sheet("模板")
    .doWrite(data);

修改默认滚动条样式
  ::-webkit-scrollbar {
    color: transparent;
    height: 3px;
    width: 3px;
  }
  :hover::-webkit-scrollbar-thumb {
    background-color: rgba(0, 0, 0, 0.2);
    border-radius: 6px;
    -webkit-box-shadow: inset 0 0 10px transparent;
  }


  修改el-table
  /deep/ .el-table{
  border-radius: 8px 8px 8px 8px;
  overflow: hidden;
  border: 1px solid #e6e6e6;
}
/deep/ .el-table::before{
  height: 0;
}
/deep/ .el-table::after{
  height: 0;
}

js比对时间

     daysBetweenDates(date1, date2) {
      // 将日期字符串转换为Date对象
      const d1 = new Date(date1)
      const d2 = new Date(date2)

      // 计算毫秒差
      const diffInMs = Math.abs(d2 - d1)

      // 转换为天数
      return Math.ceil(diffInMs / (1000 * 60 * 60 * 24))
    },

vue2 复制文本功能

# 复制

   async copyText(value) {
      try {
        // 检查浏览器是否支持 Clipboard API
        if (navigator.clipboard && navigator.clipboard.writeText) {
          await navigator.clipboard.writeText(value)
          this.feedback = '复制成功'
          this.$message({
            message: '复制成功',
            type: 'success'
          })
        } else {
          this.feedback = '浏览器不支持 Clipboard API'
          this.$message({
            message: '复制失败',
            type: 'error'
          })
        }
      } catch (error) {
        console.error('复制失败', error)
        this.feedback = '复制失败'
        this.$message({
          message: '复制失败',
          type: 'error'
        })
      }
    },

使用第三方插件 vue2

npm install vue-clipboard2 --save

在main文件引入

import Clipboard from 'vue-clipboard2'

Vue.use(Clipboard)

使用封装方法
opyText(value) {
      if (!value) {
        return
      }
      const that = this
      this.$copyText(value).then(
        function(e) {
          console.log('copy arguments e:', e)
          that.$message({
            message: '复制成功',
            type: 'success'
          })
        },
        function(e) {
          console.log('copy arguments e:', e)
          that.$message({
            message: '复制失败',
            type: 'error'
          })
        }
      )
      
    },

使用方法

<el-button type="primary" @click="copyText(text)">复制</el-button>
