More Columns in RTF(Oracle Fusion)

 Suppose we are developing the RTF report with more than 30 columns then we don't have sufficient place in the RTF even if we used the landscape. 

  In case we use the regular excel(.xls)output format in the report that doesn't provide the report output in readable format. We need to expand all columns. To avoid that we can use the 'mhtml' format. This format provides the feel good report output with proper width.
