Informations supplémentaires

This is a known limitation. The drivers make assumptions about the CSV field data types based on the first row of data. A blank (or null) value is to be translated as text. Create and modify a schema.ini file to 'force' a data type for a field in a CSV file. Additional help documentation can be found here in the following link, https://pro.arcgis.com/en/pro-app/help/data/tables/add-an-ascii-or-text-file-table.htm.

Solution de contournement

In Excel, add a single integer to the column that should be entirely null.
After the integer is added, change the data type to Numeric, and add the appropriate number of decimal places.
Save the table as a CSV, and add it to ArcGIS Pro.
The data type for the field is listed as 'Double' or 'Long', depending on the type of numeric data type selected in Excel.
Perform an operation such as 'Copy Rows', which creates a copy of the data that can be edited.
Remove the integer from the field in question.
Check the data type using 'Field View'. Note that the data type retains the proper numeric format, either 'Double' or 'Long', depending on which was chosen.
