Automate table column width adjustments in HTML using Selenium WebDriver

As of now, I am working on automating the process of increasing the width of an HTML table column using Selenium WebDriver.

I discovered that I can retrieve the coordinates of x and y by using

findElement(By.cssSelector("<Css locator>").getLocation();

However, I am curious to know if it is feasible to apply the same approach to adjusting the width of a column.

Answer №1

If you are looking to interact with elements using JavaScript in Selenium, one useful tool is the Javascript Executor

WebDriver driver;
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("document.querySelector('<CSSLOCATOR>').setAttribute('width', <WIDTH>)");

To use this method effectively, make sure to replace <CSSLOCATOR> and <WIDTH> with the appropriate values for your needs.

Answer №2

The solution to solving my problem involves the straightforward implementation of jQuery.

To achieve this, use the following code: $(selector).width(value) ;

For example: String aScript = "jQuery(\"" + CSS_TABLE_HEADER_BY_COL_NAME + "\").width(%s)";

jse.executeScript(aScript);

This method should effectively address the issue of increasing column width in Selenium for most users.

Answer №3

To modify a static table, add the attribute 'width' directly to the tag rather than using setAttribute.

String tableJS = "document.getElementsByTagName('table')[0].style.width='1000px'";
js.executeScript(tableJS);

Keep in mind that this approach may not work if the cell or table width is controlled by external CSS.

Alternatively, for a resizable table, locate the 'resizer' element and utilize the Action class with the following solution:

if (resizeableElement.isDisplayed()) {
            Actions action = new Actions(driver);
            action.clickAndHold(resizeableElement).moveByOffset(100, 100).release().build().perform();
        } else {
            System.out.println("Element was not displayed to drag");
        }
