There is an apparent bug when using the ID property to refer to cells in remote tables, which is currently the only way to refer to a table in an external file.
This is illustrated in the attached org file. In brief, the bug is triggered by any ID that contains a sequence matching the regexp "-[A-Z]+[0-9]+-", which org wants to interpret as a spreadsheet-style cell reference.
Also, it would be more user friendly if CUSTOM_ID properties could also be used in this way. Would that be easy to implement?
