合并的单元格在保存时取消合并，使用 Spreadsheet::ParseExcel

Question

我正在编写一个程序来解析一个 .xls 文件。为此，我有一个包含五个合并单元格（B1、C1、D1、E1、F1）的模板，并在其中写了“用户相关错误”。在 B2、C2、D2、E2、F2 中，我写了错误名称并希望每天保存它们的计数。代码工作正常，但在解析和保存合并的单元格（B1、C1、D1、E1、F1）后被取消合并，文本显示在 B1 中。即使在解析之后，我也需要按原样（合并）合并单元格。

我该怎么办？

Spreadsheet::ParseExcel::SaveParser 的文档指出该模块“通过使用 Spreadsheet::ParseExcel 读取并使用 Spreadsheet::WriteExcel 重写”来工作。因此，任何合并的单元格在重写时都会丢失。您将需要使用 WriteExcel 模块重新创建合并的单元格，这意味着您必须在自己的脚本中分离读取和写入。

要合并单元格，请使用带有格式的“merge_range”方法：

my $format = $workbook->add_format( align => 'left' );
$worksheet->merge_range('B1:F1', 'User-Dependent errors', $format);
