Managing column widths is crucial for readability. You can set initial sizes, define limits, or even disable automatic resizing. Setting Preferred, Minimum, and Maximum Widths Component cellComp = table.prepareRenderer(cellRenderer

// Data rows (sample up to 100) int rows = Math.min(table.getRowCount(), 100); for (int row = 0; row < rows; row++) TableCellRenderer renderer = table.getCellRenderer(row, col); Component comp = table.prepareRenderer(renderer, row, col); maxWidth = Math.max(maxWidth, comp.getPreferredSize().width);

He wrote the class by hand, line by line, feeling like a scribe copying a lost manuscript. He added a JList of JTextArea objects as a cache to improve performance. He calculated the row height dynamically in the JTable 's prepareRenderer method.

He launched the application.
