* Hello,
I have just installed TablePress and started evaluating its suitability
for our purposes. The issue I have come across is when adding html to a cell.
When I view the page containing the table in a browser I’m shown a “Message from
webpage” alert box with the following message:
* “DataTables warning (table id = ‘tablepress-1’):Requested unknown parameter ‘
2’ from the data source for row 2”
* This occurs with any html code I tried and occurs in IE 9, Chrome 25 and Firefox
19 (Windows machine). I’ve searched all 17 pages of support topics and have not
found any mention of this issue. Did I miss something in the plugin setting or
is this an unreported bug?
* Thanks,
Sofia

* Hi,
* thanks for your post, and sorry for the trouble.
* When this happens, either the HTML is invalid, or you are using the colspan/rowspan
feature.
If you post the link to the page with the table, I’ll gladly take a
look.
* Regards,
Tobias

* Thanks for the quick reply, Tobias.
* I did have a rowspan in my table and can confirm that removing the rowspan results
in an alert-free loading of the page. So how do I have both – use rowspan and
html code within cells?
* I would need to provide you with login details in order for you to view the page
so I prefer to email these details directly to you instead of posting them in
a forum. Let me know if you still need to view the page and how I can send the
details to you.
* Thanks,
Sofia

* Hi Sofia,
* ok, then the rowspan was the problem. (No need for me to view the site anymore,
therefore.)
* You can use HTML code without problems, but unfortunately, you can not use the
rowspan/colspan feature and the features of the DataTables JavaScript library(
like search, sort, and pagination) at the same time. Tables with rowspan/colspan
are not supported properly by that library.
So, basically, you’ll have to decide
what’s more important: rowspan/colspan or the features of the JS library. Then,
either remove all colspan/rowspan from the cells, or uncheck the “Use DataTables”
checkbox.

Tobias
