Object [][] data={
{null, null, null, null,null,null,1},
{2, 3, 4, 5, 6, 7, 8},
{9, 10, 11, 12, 13, 14, 15},
{16, 17, 18, 19, 20, 21, 22},
{23, 24, 25, 26, 27, 28, 29},
{30, 31, null, null, null, null,null}
};
String [] head={
"日", "一", "二", "三","四","五","六"
};
JTable jTable1=new JTable(data,head);
jTable1.setRowHeight(40);
jTable1.setAutoResizeMode(javax.swing.JTable.AUTO_RESIZE_OFF);
JScrollPane jScrollPane1=new JScrollPane();
jTable1.setCellSelectionEnabled(true);
jTable1.setFont(new Font("SimSun", 0, 20));
jTable1.getTableHeader().setFont(new Font("SimSun",0, 20));
jTable1.getTableHeader().setReorderingAllowed(false);
jTable1.getTableHeader().setResizingAllowed(false);
jTable1.setEnabled(false);
TableColumn column=null;
for(int i=0;i<7;i++){
column=jTable1.getColumnModel().getColumn(i);
column.setPreferredWidth(60);
}
DefaultTableCellRenderer tcr = new DefaultTableCellRenderer() {
public Component getTableCellRendererComponent(JTable table,
Object value, boolean isSelected, boolean hasFocus,
int row, int column) {
if((column == 0&&row!=3)||column == 6||(column == 3&&row==3))
setBackground(new java.awt.Color(255, 255, 0));
else
setBackground(new Color(255,255,255));
return super.getTableCellRendererComponent(table, value,
isSelected, hasFocus, row, column);
}
};
for(int i=0;i<7;i++){
jTable1.getColumn(head[i]).setCellRenderer(tcr);
}
jScrollPane1.setViewportView(jTable1);
