JTable... needs to be updated....

Question

Hello...
I am using a JTable in my application....
Now I need to update a JTable...
The Operation I need to preform are
1). Add new row to the table..
2). manipulate a cell value based on the rows first column value..
I want to search for the first column names and if it matches with another
value then that rows 3rd cell needs to be updated with new value....
How to do it...
I am using a abstract table model...and the code in given below...
If I can get some sample code along with some suggestion, It will be helpful.
///////////////////////////////////////////////CODE////////////////////////////////////////////////
createColumn();
createData();
TableModel ProTypTabMod = new AbstractTableModel(){
public int getColumnCount(){return ColumnNames.length; }
public int getRowCount(){return DataValues.length;}
public Object getValueAt(int row, int col){return DataValues[row][col]; }
public String getColumnName(int col){return ColumnNames[col];}
public Class getColumnClass(int col) {return getValueAt(0,col).getClass();}
public void setValueAt(Object aValue, int row, int col){DataValues[row][col] = (String)aValue; }
ProTypeTable = new JTable(ProTypTabMod);
TableColumn tc = null;
for(int i=1;i<5;i++){
tc = ProTypeTable.getColumnModel().getColumn(i);
tc.setCellRenderer(new SummColorRenderer());
/////////////////public void createColumn() {
ColumnNames = new String[5];
ColumnNames[0] = "Process Type";
//ColumnNames[1] = "Started Time";
ColumnNames[1] = "OK";
ColumnNames[2] = "On Hold";
ColumnNames[3] = "Late";
ColumnNames[4] = "Exceptions";
////////////////////////// public void createData(String[][] ContrInfo){        
DataValues = ContrInfo;
/////////////////////////// based on process type I want to change the values of Ok, OnHold, Late, Exceptions....

Answer 1

use DefaultTableModel with Vectors for Data and Columns.
Vectors rows=new Vector();
Vector columns= new Vector();
columns.addElement("ID");
columns.addElement("Name");
columns.addElement("Sal");
Vector temp=new Vector();
temp.addElement("1");
temp.addElement("ABCD");
temp.addElement("9000");
rows.addElement(temp);
DefaultTableModel tabModel=new DefaultTableModel();
tabModel.setDataVector(rows,columns);
table=new JTable(tabModel);as you go on adding values in rows vector using temp vector
you will find rows are getting added in JTable. Simillarly you can delete
the row by removing element from rows vector.
you can implement TableModel listener to find out changes.
