Show only defined columns on inserted rows

When we were inserting a row or replacing an existing one (just like we
do when we click the link to select an investment), we were entering a
row containing all columns, and all of them were displayed even if they
had been excluded using the column selector.

This caused the table to move in a strange way, which sometimes made the
investment selection tests fail.
