I'm using Aspose Cells for Java 188.8.131.52.
Some cells of my worksheet (B9:10 and C9:10 on joined Template.xlsx file) are vertical formatted on merge cells).
When I save the Excel file as PDF with Excel, these cells are well formatted (cf Template_SAVEAS_EXCEL.pdf).
But when I save the same file as PDF whith Aspose cells, "##" appears. (cf Template_SAVEAS_ASPOSE.pdf).
It seems that ASPOSE don't detect that target cells are merged and considers there is not enough place to display value.
