How to display files icons in a row with name as tooltip

Hi
I have advance file uploaded and multiple files uploaded. Then in view settings i choose show Icon and show customer expression. I kept custom expression blank so it removed file name to display. It display file icons only but in vertical seems there is some <br> code in view page.
What i want to achieve is to show file icons in row (horizontal) and file name as tool-tip when mouse over the icon.
Any idea, how do i achieve this.Thanks in advance
