jQuery - my first functions

I still remember how hard it was to make something like this working before the APEX version 4.0. You needed to create a function and then attach it to each column in your tabular form. Debugging and making changes is the next issue you had to think about. Now, using jQuery it is just a two three simple steps solution with almost no hardcoding and tricks. Also, the number of code lines you need to write is quite moderate. See this example in my demo application:
