As pointed out by others, the concept of a vertical rule does not fit in with the original ideas behind the structure and presentation of HTML documents. However, these days (especially with the proliferation of web-apps) there are is a small number of scenarios where this would indeed be useful. For example, consider a horizontal navigation menu fixed at the top of the screen, similar to the menu-bar in most windowed GUI applications. You have several top-level menu items arranged from left-to-right which when clicked open up drop-down menus. Years ago, it was common practice to create this with a single-row table, but this is bad HTML and it is widely recognised that the correct way to go would be a list with heavily customised CSS. Now, say you want to group similar items, but add a vertical separator in between groups, to achieve something like this: <pre><code>[Item 1a] [Item 1b] | [Item 2a] [Item 2b] </code></pre> Using <code><hr style="width: 1px; height: 100%; ..." /></code> works, but may be considered semantically incorrect as you are changing what that element is actually for. Furthermore, you can't use this within certain elements where the HTML DTD allows only inline-level elements (e.g. within a <code></code> element). A better option would be <code></code>, however not all browsers support the <code>display: inline-block;</code> CSS property, so the only real inline-level option is to use an image like so: <code><img src="pixel.gif" alt="|" style="width:1px; height:100%; background:#000; margin: 0 2px;" /></code> This has the added advantage of being compatible with text-only browsers (like lynx) as the pipe character is displayed instead of the image. (It still annoys me that M$IE incorrectly uses alt text as a tooltip; that's what the title attribute is for!)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
