html table tags and jquery

[soheil]

hello my friends

i have one table which is made by html tags :
<table width=100% border=1 style="display:none" id="headerTbl">
<colgroup width=200 />
<tr>
<th width="10%">X </th>
<th width="10%">Y </th>
<th> ..........."here is my question" ???????? </th>
</tr>

I want to get the name of third column from some items that I select from first col and second col...
first col and second col will be filled with some data which are stored in database then, name of third col should be pair of selected items from first and second column.in this way " item from 1st col - item from 2nd col"
I think that with jquery and with onclick function can do that but I don't know how?
how can I do this ?

any help will be appreciated
thanks in advance

this is not really a PHP question (though PHP may be involved in getting the data via AJAX) but the main issue is how to grab X and Y and then use AJAX to get the answer and fill in the field.

Since you main issue is Javascript related I am moving this post there.

And since it was asked specifically about jQuery and it is a JavaScript framework, I’m moving this thread to the frameworks section.
