Details information at the row below is outdated model and also it looks odd. 

You can show all the information in the mouse hover (using DIV) of row (OR) you can show the details icon for click action to show more information. 

If you show the mouse hover for the row, you can add some primary actions also like "details, add note, add payment, add credit etc...."

I hope this will help you.

Thanks
