//设置列宽：适应单元格内容 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 + 10); } }

设置行高：

jTable.setRowHeight(25);

此种方式会导致，当列宽超出JScorllPane大小时，不出现滚动条。此时需要设置：

jTable.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
