    public static void important(String[] args) throws InterruptedException {                                    

        // declaration and instantiation of objects/variables        

        WebDriver driver = new FirefoxDriver();

        driver.handle().window().maximize();
        driver.get("http://beta-app.1bridge.in/#/auth/login"); 
        Thread.sleep(6000);

        Listing listOfRows = (Listing) desk.findElements(By.tagName("tr"));

        System.out.println("Rows: "+listOfRows.dimension());

        //Listing<WebElement> listOfCols = listOfRows.get(0).findElements(By.tagName("td")); //If first row is regular row

        Listing<WebElement> listOfCols = ((WebDriver) listOfRows).get(0).findElements(By.tagName("th")); //If first row is header row

        System.out.println("Columns: "+listOfCols.dimension());
    }
