jtable自适应列宽度

使用：把要设置自适应宽度的jtable传入既可。
为了显示效果，每个列宽我还额外加了10px，如果想修改这个值，可以修改column.setWidth(width + myTable.getIntercellSpacing().width + 10);

/** * 使jtable自适应列宽度 * @param myTable */public static 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);        column.setWidth(width + myTable.getIntercellSpacing().width + 10);    }}
