public void FitTableColumns(JTable myTable){
??JTableHeader header = myTable.getTableHeader();
?????int rowCount = myTable.getRowCount();

?????Enumeration columns = myTable.getColumnModel().getColumns();
?????while(columns.hasMoreElements()){
?????????TableColumn column = (TableColumn)columns.nextElement();
?????????int col = header.getColumnModel().getColumnIndex(column.getIdentifier());
?????????int width = (int)myTable.getTableHeader().getDefaultRenderer()
?????????????????.getTableCellRendererComponent(myTable, column.getIdentifier()
?????????????????????????, false, false, -1, col).getPreferredSize().getWidth();
?????????for(int row = 0; row<rowCount; row++){
?????????????int preferedWidth = (int)myTable.getCellRenderer(row, col).getTableCellRendererComponent(myTable,
???????????????myTable.getValueAt(row, col), false, false, row, col).getPreferredSize().getWidth();
?????????????width = Math.max(width, preferedWidth);
?????????}
?????????header.setResizingColumn(column); // 此行很重要
?????????column.setWidth(width+myTable.getIntercellSpacing().width);

在表格数据变化后，请调用FitTableColumns(yourTableName);

网上很多，我试过，但大多不起作用，目前为止只发现这个行
