Hi
Are you talking about AEM OOTB component?
If so, then
copy table component here:
/libs/foundation/components/table
place under /apps/<yourproject>/components
Then open the code here:
/apps/<yourproject>/components/table/table.jsp.
Add your style changes to the code. You can include a clientlibs too that contains a CSS.
Make sure you change the title (the jcr:title prop of the table compoent under /apps) of the component too so you can easily see the new component. Name it something like NewTable.
Thanks and Regards
