With the current implementation when exporting a Stitching function all the containing functions are exported as Sampled functions even if they originally have been imported as Exponential interpolation functions, which leads to an increase in the size of the document.

More information can be found in the PDF Specification.

Splitting a row leads to copying all rows below it. During that operation, the information for the row height is lost, when the previous row has a cell spanning on the split one, leading to a missing row in the exported document.

The issue is a regression introduced in R1 2021.

When a row has two cells and the content of the first one is large, the width of the second cell results in too small value while measuring and its content remains invisible.

Workaround: Set PreferredWidth to the second cell.

When a Table consisting of one TableRow that contains a TableCell with a Rowspan > 1 set, additional lines are added to the table.

Table table = new Table();
TableRow row = table.Rows.AddTableRow();
row.Cells.AddTableCell();
TableCell secondCell = row.Cells.AddTableCell();
secondCell.RowSpan = 2;
table.Measure();
table.Rows.AddTableRow();

According to the PDF Specification: The first entry in the table (object number 0) is always free and has a generation number of 65,535;
