Disconnected table shows all the values in columns of matrix even though there are no values.

I have Fiscal week values in columns that comes from a disconnected table because I need a sparkline at the end of all the Fiscal weeks(SVG used to recreate the volumes and sparklines). In the rows are the customer  names. This records sales volumes per fiscal week.
Now Fiscal weeks in the column matrix shows all the future weeks with blank data. Is there a way to not to show these weeks?
