Report view is not utilizing full column width

[r.knorrek]

Hello,

I have the following problem when viewing a report in JasperReports Server:

Whenever I open a report table for viewing, in every column not the full width of the column is utilized to display the contents. See the attached picture:

In every cell in the picture, the values should be able to easily fit into a single line. This problem persists in all columns across all reports.

The Text Fields/Static Texts in every column are exactly the same width as the columns themselves. In the preview in JasperReports Studio, everything looks fine, only once the report is viewed on JasperReports Server, the problem occurs.

I am using JasperReports Server 6.3.0 and Jaspersoft Studio 6.3.1.

Thanks for your help.
