代码如下
import Java.awt.Component; import java.awt.Dimension; import java.awt.FontMetrics; import javax.swing.JLabel; import javax.swing.JTable; import javax.swing.UIManager; import javax.swing.table.DefaultTableCellRenderer; import javax.swing.table.JTableHeader; import javax.swing.table.TableColumnModel; public class Main extends DefaultTableCellRenderer { private static final long serialVersionUID = 1L; public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { JTableHeader header = table.getTableHeader(); setForeground(header.getForeground()); setBackground(header.getBackground()); setFont(header.getFont()); setOpaque(true); setBorder(UIManager.getBorder("TableHeader.cellBorder")); // 得到列的宽度 TableColumnModel columnModel = table.getColumnModel(); int width = columnModel.getColumn(column).getWidth(); value = getShowValue(value.toString(), width); setText(value.toString()); setSize(new Dimension(width, this.getHeight())); setHorizontalAlignment(JLabel.CENTER); return this; } private Object getShowValue(String value, int colWidth) { FontMetrics fm = this.getFontMetrics(this.getFont()); int width = fm.stringWidth(value.toString()); int test = fm.stringWidth("好"); System.out.println(test * value.length()); System.out.println(width); if (width < colWidth) { return value; } StringBuffer sb = new StringBuffer("<html>"); char str; int tempW = 0; for (int i = 0; i < value.length(); i++) { str = value.charAt(i); tempW += fm.charWidth(str); if (tempW > colWidth) { sb.append("<br>"); tempW = 0; } sb.append(str); } sb.append("</html>"); return sb.toString(); } }
运行结果
