用数据库内容填充SWT表

Question

I am using PhpMyAdmin to save my data in database. I have a SWT table to populate with database content.

here is my code..

public static void fetchDatafromDB(String StartIndex, String FinalIndex) {
    try {
        Class.forName(GlobalVariables.SQL_driver).newInstance();
        Connection conn = DriverManager.getConnection(GlobalVariables.DB_url + GlobalVariables.DB_name, GlobalVariables.DB_Username, GlobalVariables.DB_password);
        Statement st = conn.createStatement();
        String query = "SELECT  `From`, `To`, `IDno`, `TimeStamp` FROM `callsheet` WHERE TimeStamp BETWEEN '" + StartIndex + "' AND '" + FinalIndex + "'";
        ResultSet rs = st.executeQuery(query);
        java.sql.ResultSetMetaData rsmd = rs.getMetaData();
        int columnsNumber = rsmd.getColumnCount();
        while (rs.next()) {
            for (int i = 1; i <= columnsNumber; i++) {
                // System.out.print(rs.getString(i));
                item.setText(i, rs.getString(i));
            }
            // System.out.println();
        }
    } catch (Exception P) {
        P.printStackTrace();
    }
}

it worked.

Now I am getting some problem with tabling the DB content in my swt table. What my program does, is that, it sets the selected (defined by limit in program above) content of DB in one row (one by one manner) but I want the next row of DB table to be tabled in next row of SWT table. Could you suggest something about this? ! Screenshot of my swtTable

It should look something like this:

public static void fetchDatafromDB(String startIndex, String finalIndex) {
    try {
        Class.forName(GlobalVariables.SQL_driver).newInstance();
        Connection conn = DriverManager.getConnection(GlobalVariables.DB_url + GlobalVariables.DB_name, GlobalVariables.DB_Username, GlobalVariables.DB_password);
        Statement st = conn.createStatement();
        String query = "SELECT  `FROM`, `To`, `IDno`, `TimeStamp` FROM `callsheet` WHERE TimeStamp BETWEEN '" + startIndex + "' AND '" + finalIndex + "'";
        ResultSet rs = st.executeQuery(query);
        java.sql.ResultSetMetaData rsmd = rs.getMetaData();
        int columnsNumber = rsmd.getColumnCount();

        TableItem item;
        while (rs.next()) {
            // Create a new TableItem for each entry in the result set (each row)
            item = new TableItem(table, SWT.NONE);
            for (int i = 1; i <= columnsNumber; i++) {
                // Populate the item (mind the index!!)
                item.setText(i - 1, rs.getString(i));
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}
