To properly switch to the newly opened Tab you need to induce WebDriverWait for the New Tab to render and then through a for()
loop you need to iterate through the available WindowHandles and invoke switchTo().window()
with the WindowHandle which is not the previous TAB through the following code block :
String first_handle = driver.getWindowHandle();
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("arguments[0].click();", tableRow);
new WebDriverWait(driver,5).until(ExpectedConditions.numberOfWindowsToBe(2));
Set<String> allHandles = driver.getWindowHandles();
for(String winHandle:allHandles)
{
if (!first_handle.equalsIgnoreCase(winHandle)
{
driver.switchTo().window(winHandle);
}
}
