我想调整jtable中特定单元格的大小,以便在文本大小大于某个大小时自动设置。这就是我向我的表添加内容的方式。
if(rs.next()) {
rs.beforeFirst();
Vector<String> columnNames = new Vector<String>();
columnNames.add("Tweet");
columnNames.add("Updated Time");
Vector<Vector<Object>> data = new Vector<Vector<Object>>();
while (rs.next()) {
Vector<Object> vector = new Vector<Object>();
Tweet = rs.getString(1);
vector.add(Tweet);
SimpleDateFormat sdf = new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Timestamp time = rs.getTimestamp(2);
Updated_time = sdf.format(time);
vector.add(Updated_time);
data.add(vector);
}
DefaultTableModel dfm = new DefaultTableModel(data, columnNames);
JTable table = new JTable(dfm);
table.setAutoscrolls(true);
table.setShowGrid(false);
((DefaultTableCellRenderer)table.getDefaultRenderer(Object.class)).setOpaque(false);
table.setOpaque(false);

public class MyRenderer extends JTextArea implements TableCellRenderer {
private static final long serialVersionUID = 1L;
public MyRenderer() {
setLineWrap(true);
setWrapStyleWord(true);
setOpaque(true);
}
@Override
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus,
int row, int column) {
// TODO Auto-generated method stub
setText(value.toString());//or something in value, like value.getNote()..
if (isSelected) {
setForeground(table.getSelectionForeground());
setBackground(table.getSelectionBackground());
} else {
setForeground(table.getForeground());
setBackground(table.getBackground());
}
setSize(table.getColumnModel().getColumn(column).getWidth(),
getPreferredSize().height);
if (table.getRowHeight(row) != getPreferredSize().height) {
table.setRowHeight(row, getPreferredSize().height);
}
return this;
}
}

JTable单元实际上显示的是JLabel,因此对于文本换行,您可以应用html,如:
"<html>" + "Your value" + "<br>" + "Desc"
