[visualization-api] Table visualization with cell selection

[Renato Beserra]

Hi, I noticed that the Table visualization doesn't have a cell selection policy.

Anybody knows why?

Is there any known workaround to enable it?

Thanks!

You can use regular js event listeners on the table's 'td' elements to get the column index.  Here's an example (with a bit of help from jQuery): http://jsfiddle.net/2Vtwb/

Thanks for the answer.

Do you know if I can disable the select event of the table? I will have to override the css style to show the cell selection policy and the row selection can be a problem.

You can override the existing css by using the cssClassNames option: http://code.google.com/apis/chart/interactive/docs/gallery/table.html#Configuration_Options

I have a vague recollection that there used to be an option to disable interactivity in the charts, though I can't seem to find it for the tables.  If you do find a way to disable the selection event, you'll have to use standard js to grab the row index too, but that's not difficult: http://jsfiddle.net/2Vtwb/1/

Thank you very much! If I find something else useful I will share later.

Now I'm curious - is there a reason the Table chart doesn't implement
identify which column was clicked on? Is this something that's more
complicated than I imagine, or are there some situations where this
becomes difficult?

Since the Table provides a listener that tells us what row was clicked
on, it'd be nice if it did the same for columns. If we can code this
ourselves in js, seems like we can code the same for the Google class
once so that everyone can use it. If someone has a good listener
codes, perhaps it can be posted so the GVIZ team can incorporate it
into the codebase?

asgallant - when I first saw you mention using regular js, I was
surprised that you didn't mention jQuery. I was greatly relieved when
I read your second sentence ;) (kiddding - I've learned a lot from
your posts showing how to use jQuery in conjunction with the GVIZ
API. It has made jQuery that much more useful for me).

You're right that the Table visualization doesn't support column selection, only row selection. Since augmenting the Table visualization is not high on our priority list, I can't promise it happening any time soon...
