Bug in Excel2003XML reader, parsing merged cells

[bobwitlox]

The Excel2003XML reader class handles merged cells incorrectly when a row contains multiple merged cells. It does not increment the column counter correctly, so the subsequent merged cells have the wrong column ID.

Bugfix:

Line 602-614:

$additionalMergedCells = 0; // bugfix
if ((isset($cell_ss['MergeAcross'])) || (isset($cell_ss['MergeDown']))) {
  $columnTo = $columnID;
  if (isset($cell_ss['MergeAcross'])) {
    $additionalMergedCells = (int)$cell_ss['MergeAcross'];  // bugfix
    $columnTo = PHPExcel_Cell::stringFromColumnIndex(PHPExcel_Cell::columnIndexFromString($columnID) + $cell_ss['MergeAcross'] -1);
  }
  $rowTo = $rowID;
  if (isset($cell_ss['MergeDown'])) {
    $rowTo = $rowTo + $cell_ss['MergeDown'];
  }
  $cellRange .= ':'.$columnTo.$rowTo;
  $objPHPExcel->getActiveSheet()->mergeCells($cellRange);
}

Line 765-769:

// bugfix
while ( $additionalMergedCells > 0 ) {
  ++$columnID;
  $additionalMergedCells--;
}
