html – Problem displaying side tab navigation in IE7 – Education Career Blog

I am attempting to build a “Tabbed” side navigation menu using html/css.

I am going with the most convenient approach of using a table that has a single row and two cells (columns). The left cell is for the “tabs” and the right cell is for the content to be displayed. The left cell containing the tabs has a right border set to be the divider between the tabs and the content.

Each “Tab” is a div tag within this cell. I then want to eliminate this right border for the selected “Tab”. To achieve this I am setting the selected “Tab” div with a margin-right of -1px. The idea is this will essentially offset that div to cover the right border that is set in the underlying table cell. This mechanism works fine in Firefox and Safari, but does not work in IE7. Anyone have an idea on how to get this tor work in IE7?

Note… I have not checked this in IE8 as of yet.

Here is the html…
