I have a web page that contains a data table I want to make the first column cells redirect the user to another pages depend on its value so I want first to get the value from a cell second to make a link from this cell to another page depend on that value.
any advises.
You need to write a custom cell formatter. Check the documentation for whichever version of YUI you are using:
