如何用硒驱动器减少表中的列宽

Question

I am automating one functionality on certain website where I want to resize the column 'Description' of table, but while doing same with below mentioned code, getting some kind of warning or error and same is not happening.

//This is Description column for which I want to change the width

    WebElement descr = driver.findElement(By.linkText("Description"));

    WebDriverWait wait = new WebDriverWait(driver, 25);
            wait.until(ExpectedConditions.visibilityOfElementLocated(By.linkText("Description")));

    int width_descr = descr.getSize().getWidth();
    int height_descr = descr.getSize().getHeight();
    System.out.println("Width of Description ="+width_descr);
    System.out.println("Height of Description ="+height_descr);

    int half_height_descr= height_descr/2;
    System.out.println("Half of Height of Description ="+half_height_descr);

    //Logger.getLogger("org.openqa.selenium").setLevel(Level.SEVERE);

    Actions builder = new Actions(driver);

    Action resizable = builder
            .moveToElement(descr, width_descr, height_descr)
            .clickAndHold()
            .moveByOffset(width_descr, 0)
            .release()
            .build();

    resizable.perform();

}

Actual output as below:-

Width of Description =242
Height of Description =27
Half of Height of Description =13

Apr 01, 2019 8:35:54 PM org.openqa.selenium.interactions.Actions moveToElement

INFO: When using the W3C Action commands, offsets are from the center of element--This is the warning i am getting in console.

and column width not getting reduced on UI.

Expected output:- I want to reduce the column width.

If this is HTML5 form - you cannot do that with Actions class as well as with Robot framework.

You can try to make screenshot of web element and interact it with Sikuli library, eg: https://github.com/alexandrchumakin/Relay42ApiTest/blob/master/src/main/java/web/driver/WebDriverHelper.java#L35

Or you can implement JQuery that will do all this magic.
