I have used Spreadsheet::WriteExcel for creating spreadsheet report.

I tried to merge some cells using merge_range() function.

$worksheet->merge_range(3,5,9,4,$title,
$format);
[OR]

$worksheet->merge_range(‘E3:I4’,$title,
$format);

$worksheet->write(‘F6’,”LANGUAGE”,$format);

it shows the error message like the following

Error: refer to merge_range() in the
documentation. Can’t use previously
merged format in non-merged cell

How to solve this. if I used write() .. that time only it shows the error. if I didn’t used any write functions that time the above error message is not showing and the cells are merged.

    If you see the documentation of Spreadsheet::WriteExcel module, it states :

    WARNING: The format object that is used with a merge_range() method call is marked internally as being associated with a merged range. It is a fatal error to use a merged format in a non-merged cell. Instead you should use separate formats for merged and non-merged cells. This restriction will be removed in a future release.

    That means do not use format ‘$format’ as used in the

    $worksheet->write('F6',"LANGUAGE",$format);

    Make two format one for merged cell other for non-merged cell.

    Problem will be solved.
