Colspan All Columns


Answer :

Just use this:

colspan="100%"

It works on Firefox 3.6, IE 7 and Opera 11! (and I guess on others, I couldn't try)

Warning: as mentioned in the comments below this is actually the same as colspan="100". Hence, this solution will break for tables with css table-layout: fixed, or more than 100 columns.


I have IE 7.0, Firefox 3.0 and Chrome 1.0

The colspan="0" attribute in a TD is NOT spanning across all TDs in any of the above browsers.

Maybe not recommended as proper markup practice, but if you give a higher colspan value than the total possible no. of columns in other rows, then the TD would span all the columns.

This does NOT work when the table-layout CSS property is set to fixed.

Once again, this is not the perfect solution but seems to work in the above mentioned 3 browser versions when the table-layout CSS property is automatic. Hope this helps.


If you want to make a 'title' cell that spans all columns, as header for your table, you may want to use the caption tag (http://www.w3schools.com/tags/tag_caption.asp / https://developer.mozilla.org/en-US/docs/Web/HTML/Element/caption) This element is meant for this purpose. It behaves like a div, but doesn't span the entire width of the parent of the table (like a div would do in the same position (don't try this at home!)), instead, it spans the width of the table. There are some cross-browser issues with borders and such (was acceptable for me). Anyways, you can make it look as a cell that spans all columns. Within, you can make rows by adding div-elements. I'm not sure if you can insert it in between tr-elements, but that would be a hack I guess (so not recommended). Another option would be messing around with floating divs, but that is yuck!

Do

<table>     <caption style="gimme some style!"><!-- Title of table --></caption>     <thead><!-- ... --></thead>     <tbody><!-- ... --></tbody> </table>

Don't

<div>     <div style="float: left;/* extra styling /*"><!-- Title of table --></div>     <table>         <thead><!-- ... --></thead>         <tbody><!-- ... --></tbody>     </table>     <div style="clear: both"></div> </div>

Are Regular VACUUM ANALYZE Still Recommended Under 9.1?

Answer : VACUUM is only needed on updated or deleted rows in non-temporary tables. Obviously you're doing lots of INSERTs but it's not obvious from the description that you're also doing lots of UPDATEs or DELETEs. These operations can be tracked with the pg_stat_all_tables view, specifically the n_tup_upd and n_tup_del columns. Also, even more to the point, there is a n_dead_tup column that tells, per table, how much rows need to be vacuumed. (see Monitoring statistics in the doc for functions and views related to statistics gathering). A possible strategy in your case would be to suppress the scheduled VACUUM, keeping an eye on this view and checking on which tables the n_dead_tup is going up significantly. Then apply the aggressive VACUUM to these tables only. This will be a win if there are large tables whose rows never get deleted nor updated and the aggressive VACUUM is really necessary only on smaller tables. But keep running the ANALYZE for the optimiz

Can Feynman Diagrams Be Used To Represent Any Perturbation Theory?

Answer : Diagram machinery works also for perturbation theory in classical statistical mechanics and classical field theories. Generally, various kinds of diagrams constitute a pictorial way of talking about tensor products and their contractions while hiding the multi-linear algebra from the layman. In the simplest case, vertices (or blobs) represent vectors, matrices, tensors; vertices have ingoing and/or outgoing ports; ingoing ports denote (contravariant) ro indices; outgoing ports denote (covariant) co indices; directed arcs between blobs give a pair of equal indices summed over; different base spaces ⇔ \Leftrightarrow ⇔ different arc types; symmetric tensors ⇔ \Leftrightarrow ⇔ undirected diagrams; no labels are needed for internal lines. In many cases, the directed arcs are decorated (as thin, thick, broken,wavy, curly lines), each decoration indicating the presence of a so-called propagator, a function of its label to use as a weight in the sum, which may beco
