How to count the number of headers in a web table in Selenium?

The total number of headers in the web table can be counted with the help of findElements() method. The logic is to return a list of web elements with xpath with the help of <th> tag inside the table, then getting the size of that list.

Code Implementation

Example

import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import java.util.concurrent.TimeUnit;
import java.util.List;
public class TableHeaderCount {
   public static void main(String[] args) {
      System.setProperty("webdriver.chrome.driver",       "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe");
      WebDriver driver = new ChromeDriver();
      String url = "https://www.tutorialspoint.com/plsql/plsql_basic_syntax.htm";
      driver.get(url);
      driver.manage().window().maximize();
      driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
      // xpath with index appended to get the header
      //from the row 1 of table with the help of <th> tag
      List<WebElement> header = driver.findElements(By.xpath("//table/tbody/tr[1]/th"));
      System.out.println(“The number of table headers is “+ header.size());
      driver.close();
   }
}
