How to set column-width dynamically

[Johannes Wolfgang Woger]

Hallo, I am using FOP with JSP pages. I have one printTable.jsp page that fits almost all Table representations. It therefore does not know the row count and the Column count in advance. I would like to make a printTableFO.jsp with the same dynamic elements.   How can I set column-width dynamic <fo:table-column column-width=”proportional-column-width(‘${calculatedWidth}’)”> Does not work. Can any values of FOP attributes be set dynamically?               Wolfgang
