Thank you very much for all your recommendations. I've looked at a few jQuery grid plug-ins and at the DHTMLX grid tool, but hadn't the time to do a in-depth comparison.
>From the online demos I saw, the extjs grids seem to be still the most intuitive to use from a user perspective. Can't say anything about how easy they are to implement. Things I like on the extjs grids: Very responsive. Single click cell editing. The edit field overlays the original value and is not shifted to the left, like with the DHTMLX example. Lot of little helpers available in the edit field, like value up/down arrows, pulldowns, calendar view etc. Don't know, whether this can be generated with one of the jQuery grid plug-ins or the DHTMLX grid tool as well, at least they don't demo it. I still wasn't able to get a definite answer, whether you you have to publish your source code, if you want to use ExtJS or DHTMLX within your website. And in case you have to publish the code, what part of the code, only the extjs code you have altered (which frankly is always published as you have to send the code to browser to work) or the whole code, that generates the output including all html, php, css, other javascript, the A4D code and even the 4D code or what else you might use. Even though I have no intention to sell my online catalog to anyone, publishing the source code is out of question, simply for security reasons. Browsing the web for GPL and web applications left even more questions unanswered, than I originally had, and my email to Sencha asking for their interpretation of the GPL in respect to websites has not been answered so far. I have the impression, that the GPL was intended for apps that are shipped and not for web applications or websites and using GPL licensed components in your website is bit of a gray zone and it seems that some companies deliberately do nothing to clarify things probably due to commercial reasons. Don't get me wrong. Developers deserve to earn money with their products, but in the case of extjs a commercial license for $600 is ways out of proportion, if you just want to offer you customers a nicer way to edit their shopping cart. In case someone went already through the cumbersome process of finding out how the GPL applies to websites, I'd appreciate to hear your findings. If you don't want to post it to the list, send it to me directly.
