Pablo,

You can't have your cake and eat it too. You wanted to now how to insert a new column in a specific position wihtout moving all the property settings around, well that is how you do that. If the name is important then move the properties around, or even better, name your columns with a meaningful name like colName, colAddr1, colAddr2, colCity etc. Then who cares which column is where.
