Vizlib Table export - indication for users to know the data is exporting

We are using Vizlib table to extract data from a table which might contain ~70000 records with 40 dimension fields. While exporting the data in "Formatted Excel", it is not giving any indication to the user that the data is exporting or not. This would be a nice to have feature for the Vizlib table object. I believe this feature is available in Vizlib pivot table object.
