3.1EA: Spacing broken in SQL Worksheet (worked in 3.0)

Question

I have version 3.1.05.97 - not sure if that's EA1 or EA2 (why doesn't Help > About contain the text EA1 or EA2?)
Run this command:
select * from v$session;
Then scroll to the right. In 3.1, the spacing for the heading doesn't match the column data. The problem starts in the 2nd column: the heading for SID is only 3 characters wide, but the data is 4 characters wide. Every column gets progressively worse.
The same command in 3.0.04.34 looks correct, even when scrolling to the last column.

Answer 1

I have no detailed knowledge of what changed in this area between 3.0 and 3.1, but I would agree it's a bug (Raghu, too?).
I guess Statement Runner (F9) is doing a better job of sizing the column width in 3.1, so maybe it would be easy for the developer to apply that logic to Script Runner (F5) output as well.
In terms of SQL*Plus default column width control for numeric data types, it uses:
set numwidth n
show numwidthPerhaps that could ultimately be an approach for SQL Developer to take, if and when the Worksheet supports that syntax. You might want to add that as a feature request on the SQL Developer Exchange.
