Thanks! On review, I see that JRootPane, JScrollPane and JSplitPane all return true for isValidateRoot(). In contrast, JTextField's isValidateRoot() returns false when it's contained within a JViewport, perhaps for a similar reason. -- John B.

Thanks! First of all thanks a lot for all the helpful replies, this solution works perfectly :-) However, in order to make resizing columns work, the following is necessary: headerTable.setTableHeader(dataTable.getTableHeader()); (I currently don't know why) However, when using the above line, the sorting method provided by Java 1.6 will not work any more. Luckily, the following solution for java 1.5 works perfectly: http://stackoverflow.com/questions/591610/jtable-sorting-rows-in-java-1-5 Now everything works: column resizing, sorting, fixed rows, no update problems :-) Thanks again! -- Felix Natter

Thanks! In fact, it works for your SSCCE, too. > However, in order to make resizing columns work, the following is > necessary: > headerTable.setTableHeader(dataTable.getTableHeader()); > (I currently don't know why) If you apply it to your SSCCE, resizing and sorting will work as expected.

JTextField returning true at all from isValidateRoot() is a misguided broken optimization.

I would disable the column layout for the header and footer. See the last section of http://www.chka.de/swing/table/column-headers/JTable-JTableHeader.html |
