        ref="saleBill"
        :data="saleBill"
        :cell-class-name="cellClassName">
</el-table>

//methods
cellClassName({row, column, rowIndex, columnIndex}){
    if((column.property == 'pack_dj' || column.property == 'pack_sl' || column.property == 'pack_order_sl') && row[column.property] <= 0 ){
        return 'zeroClass'
    }
}

.zeroClass{
