does slideToggle work with table?
I want to slideToggle a row of a table. but it just appears without any effect.
Answer
SlideToggle does work with table rows, it just kind of sucks.
If you have a table row with a height larger than it's minimum - like this
<tr height="30%">
Then slidetoggle will do a smooth slide down until the reaches it's minimum height... then it will dissapear immediately like you used
$("#tr").hide();
I've made a jsfiddle demonstrating this at http://jsfiddle.net/BU28E/1/
A better solution for you may be to use a table made out of divs. Divs will slide up very smoothly. I made another jsfiddle demonstrating this at http://jsfiddle.net/BU28E/2/
