title: Jasper HTML output width issue
body: <p>This report is generated with jasper reporting tool with REST API. Report data is showing in an HTML page with an iframe. After loading data to the iframe, report HTML view showing a lot of white spaces in the right and left side. I have tried with increasing the iframe width in CSS. But this is not affecting the report. Is it possible to adjust white spaces from jasper report itself? I am using page size as A4 landscape.</p>
