@TrucoBen123 ,
Use a select action after the filter array action, and in it create the output for HTML table, column name - value.

From -> body('Filter_array');
Map - > Key - Value.
Also, Can you take in consideration to use ODATA filter inside "List rows present in a table" instead of bringing all values to flow and filter it locally ? (this is applied only if the filter condition is not to complex, as the Excel connector doesn't support many operations).
Of course, that in this case the From from the new select action will be
(use the Add dynamic content ->expressions):
body('List rows present in a table')['value']
Hope it helps !
