[Orgmode] Suggestions on Org-table export-html

[Xin Shi]

Hi,

When I use the org-table to export-html, I have two suggestions to make the CSS 
more flexiable (it already done a great job!)

The first one is for flexiable CSS:

The current code in html is:
<table border="2" cellspacing="0" cellpadding="6" rules="groups" frame="hsides">

It'll be flexiable to add another attribute  class="org-table", so that in the 
CSS file, we can treat these tables specifically. In this way, we'll be able to 
write in the CSS file like:

table.org-table th {
    background-color: #ECF1FF;
}

without affect the generic web table. 



The second one is for cleaner view on the html table:

Currently, every row is start with <tr>, it'll be nice to have alternate row 
with class="alt":

<tr> 
...
</tr>

<tr class="alt">
...
</tr>

Then, in the CSS file, we can use:
table tr { background: #e6e6e6;}
table tr.alt {background: #f1f1f1;}

The output html table will looks better then. 


Thanks!

Xin
