I have a table that I\'ve made sortable using the jQuery plugin Tablesorter 2.0. On the same page, I have a Google Map that displays a marker for each item in the table. Now, I
I would suggest creating each row at the same time that you create each marker.
In each iteration of the loop, generate an id for that marker/row. Add the id to the row, and add a GEvent listener to the marker with the code to highlight the row of the same id. Add the marker to an array with the index of the id.
You can add a listener for the row mouseover which gets the row id, which you can use to access the related marker from the array.
If I have time later, I'll see if I can come up with some code.
