Hi, This is a fix for NPE in OldJTable.addColumn
The addColumn method in OldJTable.java was unconditionally calling columnData.toArray(), which caused a NullPointerException when columnData was null (e.g., when called from addColumn(Object, int)). This commit adds a null check to safe-guard against this NPE, passing null to the underlying DefaultTableModel when columnData is missing. Kindly review.
