Method Detail

afterSplitTable

void afterSplitTable(PdfPTable table,
                     PdfPRow startRow,
                     int startIdx)

This method is called to indicate that table has been split. It's called after the tableLayout method and after the table has been drawn on the previous page but before the rest of the table is laid out on the following page. It is meant to allow modifications of the table, e.g. by changing cells. This is useful for situations when some information has to be repeated, like putting "still " in the top cell of a column where categorizations for blocks of rows are placed, e.g.

 2012  | Jan | 1000 $ | 2000 $ 
       | Feb |  900 $ | 2100 $
 
 -------8<----- Page break -------------
 
 still | Mar | 1100 $ | 1900 $ 
 2012  | Apr | 1200 $ | 1800 $ 
       | May | 1200 $ | 2200 $
 ...
 

While this might be emulated by just stamping "still 2012" on the page using the currently available event callback tableLayout, that would fail in the case of the page break happening after the November line, because the text "still 2012" would then overlap with the new entry "2013" in the 2013 January line. This problem does not exist when modifying the first cell on the new page because that cell will the be laid out to have sufficient height so that no overlaps occur. Example:

 public void afterSplitTable(PdfPTable table, PdfPRow startRow, int startIdx) { 
     PdfPCell cell = startRow.getCells()[0]; 
     cell.addElement(new Paragraph("still " + currentYear)); 
 }
 

Note that determining the value of currentYear can be done in tableLayout by noting the sizes of the tables laid out there and comparing them with the tracked row indices of the years (via table.getRows()).

Parameters:

table - the PdfPTable in use

startRow - the first PdfPRow of the table body on the following page

startIdx - the index of that row
