Setting the jTable column width

Question

Coming from VB6 to Java is hard for me. Syntax is so much different.
Below is what I am doing to populate the jTable and the values are coming from MySQL. My problem is setting the column width but I am having difficult understanding how to do it. I looked on the website and downloaded some examples and clearly because I am new and I simply do not understand it. I was wonder if someone is willing to modify the codes below on how I should do it. Thanks
private void populate_grid(){
Vector dataVector = new Vector();
Vector columnVector = new Vector();
columnVector.add("ID#");
columnVector.add("Account Description");
columnVector.add("Contact");
columnVector.add("State");
while (myResult.next()) {
Vector rowVector = new Vector();
System.out.println(myResult.getString("acct_name"));
rowVector.add(myResult.getString("cust_id"));
rowVector.add(myResult.getString("acct_name"));
rowVector.add(myResult.getString("main_contact"));
rowVector.add(myResult.getString("main_state"));
dataVector.add(rowVector);
jTable1.setModel(new javax.swing.table.DefaultTableModel(dataVector, columnVector));

    int rows = 3;
    int cols = 3;
    JTable table = new JTable(rows, cols);
    // Disable auto resizing
    table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
    // Set the first visible column to 100 pixels wide
    int vColIndex = 0;
    TableColumn col = table.getColumnModel().getColumn(vColIndex);
    int width = 100;
    col.setPreferredWidth(width);
