    This is done not by PHP, but by means of html, Java ... Than not laziness in general ... Ajax Powered, Editable DHTML JavaScript DataGrid is a good example of implementation.

      If in general terms, make an Ajax request for the date of interest, then substitute the received values ​​in the table.
      A simpler way is ahah: the part of the table with dates is a separate page, pushed into the Iframe. The problem is that ahah in xhtml is already considered obsolete.
