实现JTable的列宽与内容的自适应

 JTable默认的各列宽度平均，下函数可以实现各列宽度与内容长度适应！来自互联网~

public void FitTableColumns(JTable myTable){  2   JTableHeader header = myTable.getTableHeader();  3      int rowCount = myTable.getRowCount();  4      Enumeration columns = myTable.getColumnModel().getColumns();  5      while(columns.hasMoreElements()){  6          TableColumn column = (TableColumn)columns.nextElement();  7          int col = header.getColumnModel().getColumnIndex(column.getIdentifier());  8          int width = (int)myTable.getTableHeader().getDefaultRenderer()  9  .getTableCellRendererComponent(myTable, column.getIdentifier() 10                          , false, false, -1, col).getPreferredSize().getWidth(); 11          for(int row = 0; row<rowCount; row++){ 12              int preferedWidth = (int)myTable.getCellRenderer(row, col).getTableCellRendererComponent(myTable, 13                myTable.getValueAt(row, col), false, false, row, col).getPreferredSize().getWidth(); 14              width = Math.max(width, preferedWidth); 15  } 16          header.setResizingColumn(column); // 此行很重要
         column.setWidth(width+myTable.getIntercellSpacing().width); 18      }

使用方法：FitTableColumns(yourTableName);
