This is how the Report Viewer's Excel renderer works. You cannot change the way it exports the excel file, however, there are other ways to resolve your issue.
My suggestion is #2 -- You can load the RDLC file in memory, and do your modifications there, then call the ReportViewer export function for that altered report.
I found the solution of the same problem! :) Set the "CanGrow" Property to False for all cells from one row. And also set the "Height" Property to your specific size.
If you have elements before your tablix this can stop the growth. I've found that removing all elements before the tablix will restore the desired row-growth/auto-fit behaviour. I have not found a better solution yet.
I've found that instead of removing any elements before the tablix, you can change their width to match that of the page.
