Working on Webtables in Selenium with the use of Java

What is Webtable?
Web tables are basically group of elements that are logically stored in a row and column format. 

1.  If we know that number or rows and Columns are fixed than we will use the below approach

1	for(int numberOfRows=1; numberOfRows<=5; numberOfRows++)

2

{

3	for(int numberOfCol=1; numberOfCol <=3; numberOfCol++)

4

{

5	System.out.println(driver.findElement(By.xpath(“//div[@id='main']/table[1]/tbody/tr[“+numberOfRows+”]/th[“+numberOfCol+”]”)));

6

}

7

}

1. 
   
2.      How to work with the dynamically changed webtables?

1	WebElement htmltable=driver.findElement(By.xpath("//*[@id='main']/table[1]/tbody"));

2	List<WebElement> rows=htmltable.findElements(By.tagName("tr"));

3

4	for(int rnum=0;rnum<rows.size();rnum++)

5

{

6	List<WebElement> columns=rows.get(rnum).findElements(By.tagName("th"));

7	System.out.println("Number of columns:"+columns.size());

8

9	for(int cnum=0;cnum<columns.size();cnum++)

10

{

11	System.out.println(columns.get(cnum).getText());

12

}
