Custom Formatting in Table Visualization is not Respected on Export to Excel for Aggregated Fields

[ixipixi]

Describe the bug

Exporting formatted data from a table visualization to Excel fails to retain the custom formatting if the fields were summarized in the underlying Question.

To Reproduce

• Create a question
• Group by some field
• In the summarize box take a sum or max of a numeric field
• Save it to a table visualization
• Format the aggregated field as currency type, percent or any other visual customization
• Export to Excel
• Note the formatting is missing

If the formatting is applied to un-summarized fields the format in the export is correct.

Expected behavior

The format in the export should match the table viz.
