<el-table
     :cell-style="{background:'#f5f5f5'}"
     >

 .el-table tbody tr:hover>td {
            background-color:#f5f5f5 !important
        }

:cell-style="setCellStyle"

setCellStyle({ row, column, rowIndex, columnIndex }) {
        if (column.label === '当前列表头的名字') {
          return "background:#e8e8e8;"//可以设置颜色或者边框
        }
        if (columnIndex === 4) {
          return "background:#e8e8e8;"
        } else {
          return "background:#e8e8e8;"
        }
      }
