Freezing Columns/Rows on Export to Excel (Angular)

[chris-work]

Is your feature request related to a problem? Please describe.

When exporting a report generated in igx-grid, users would like to have the same features/styling/frozen panes when it is exported to Excel.

Describe the solution you'd like

My preference is for something static/automatic (reads current styling/frozen panes within the existing grid), but something that is dynamic (options to be set in IgxExcelExporterOptions) would also work.

Describe alternatives you've considered

As far as I know, there is no alternative, other than users manually persisting styling/frozen panes into the downloaded template.

Additional context

For my case, it applies to large data sets, so it's important to have "pinned" columns and column headers visible at all times.

We are going to expose header freezing option, which would be included in the IgxExcelExporterOptions.
Additionally, exporting igx-grid with pinned columns is currently supported. The following sample demonstrates this functionality.
