Trying to create a new list: It is annoying that one can not create similar field names starting with a number. E.g. a list with fields with the following names: 1_spoligo, 2_spoligo, 3_spoligo... is not allowed with labKey. That is particularly annoying when already existing external data with such a field structure, needs to be imported into LabKey.

As a workaround you can use labels (and import aliases), this will allow you to import columns that look like "1_spoligo", even if the the actual database column name does not start with a number.
