JTable Column Resizing optimization guide Properly After Adding Rows Dynamically
I'm currently working on a Swing application that utilizes a `JTable` to display user data. Everything was going smoothly until I implemented functionality to add rows dynamically. After adding new rows, I've noticed that the column widths do not adjust as expected. For example, I initially set the preferred width of a column using `setPreferredWidth()` on the `TableColumn`, but it seems to reset or does not take effect after rows are added. Here's a snippet of my code: ```java DefaultTableModel model = new DefaultTableModel(new String[] {"Name", "Age", "Email"}, 0); JTable table = new JTable(model); TableColumn column = table.getColumnModel().getColumn(0); column.setPreferredWidth(150); // Adding rows dynamically model.addRow(new Object[] {"Alice", 30, "alice@example.com"}); model.addRow(new Object[] {"Bob", 25, "bob@example.com"}); ``` No matter how many rows I add, the width of the first column seems to revert to a default width or does not adjust according to my specifications. I've also tried calling `revalidate()` and `repaint()` on the table after adding rows, but it hasn’t resolved the scenario. Am I missing something in terms of updating the table or configuring the columns correctly? Is there a best practice to ensure that the column widths remain set after changing the model? Any insights into how to debug this behavior would be greatly appreciated. I'm using JDK 11 and Swing for this application.
