Pdf Export in Vue Gantt component

PDF export allows exporting Gantt data to PDF document. You need to use the pdfExport method for exporting. To enable PDF export in the Gantt, set the allowPdfExport to true.

To export data to PDF document, inject the PdfExport module in Gantt.

Note: Currently, we do not have support for exporting manually scheduled tasks.

Show or hide columns on exported PDF

You can show a hidden column or hide a visible column while exporting the Gantt using the toolbarClick and beforePdfExport events.

You can show or hide columns by setting the column.visible property to true or false respectively.

In the following example, there is a hidden column Duration in the Gantt. While exporting, we have changed Duration to visible column and StartDate to hidden column.
