Description: ------------ Excel XP crashes when generated worsheet have many column merges. Merges are become bugous when spreadsheet have about 400 of them. When count of merges is more than 700, Excel XP crushes. Test script: --------------- <?php include_once "Spreadsheet/Excel/Writer.php"; $xls =& new Spreadsheet_Excel_Writer(); $xls->send("table.xls"); $sheet =& $xls->addWorksheet('table'); for($i=0; $i<40; $i++){//change to $i<100 to get excel crush for($j=0;$j<20;$j+=2){ $sheet->setMerge($i, $j, $i, $j+1); } } $xls->close(); ?> Expected result: ---------------- A blank table, each cell must have colspan=2 and rowspan=1. Actual result: -------------- A blank table, each cell have colspan=2, but many cells from column "M" have rowspan=2. When I extend the table up to 100 rows, I get the excel crush.

Just avoided problem by using mergeCells() instead of setMerge().

Man, thank you, you have saved me a lot of headache. It was indeed sufficient to replace "setMerge" with "mergeCells". Very confusing bug...
