Export csv or xlsx file performance is so slowly via tableExport jquery plugin when the table have more than 10000 record(s), How to fix?

There already exist several issues dealing with export of large tables. Please have a look to them: #250, #195, #132, #127, #70. Perhaps those issues help you in solving yours. Finally I never figured out what caused the reported problems. There are some hints:

• The plugins export speed slows down dramatically if the table cells (all of them ?) contain style and class attributes
• Not including Filesaver.js prevents from downloading large export results
• Using bootstrap table with an outdated version of the export plugin
• The export become slow when using bootstrapTable merge columns
• Hidden elements (tr, th, td) can be one reason why the export process slows down
