html - How to over-ride CSS in content management system -

-



i'm building page on company's intranet, runs on sharepoint 2007. i'm trying use tables better organize page, appears there style sheet defines tables having borders , grey backgrounds. i'd change formatting of table, cannot find way around style sheet.

when enter html editor, have tried updating html within table, no luck. tried adding css in editor well, no dice. i'm amateur @ kind of thing, not sure how best proceed. there way over-ride css , style of table want?

how table accessed? if selected table tag in css, can't unless give tables class. if selected class, can change class 1 table want change. if want keep of attributes, make table have different id, create selector in css id, , add attributes want keep. example...

<table class = 'table'> <tr> <td>example<td> </tr> <tr> <td>example2<td> </tr> </table> <table class = 'table'> <tr> <td>example<td> </tr> <tr> <td>example2<td> </tr> </table> <table class = 'table'> <tr> <td>example<td> </tr> <tr> <td>example2<td> </tr> </table> <table class = 'table2'> <tr> <td>example<td> </tr> <tr> <td>example2<td> </tr> </table> <table class = 'table'> <tr> <td>example<td> </tr> <tr> <td>example2<td> </tr> </table>   <style> .table{ border:solid 5px black; } .table2{ border:solid 5px purple } </style>

in example, made other tables have class, , changed class 1 table wanted change.
