I have a table with header(1row) and footer(1 row). i am getting the table size and expect value as 50 but it returns 52 as it count both header and footer row. Is there a way i can exclude the header and footer row with in my code and get the actual expected value. Here is my code to get the table size

```
public int getTableSize() throws InterruptedException{
    List<WebElement> columnElements = driver.findElements(By.cssSelector("table[class='table table-bordered table-hover ng-isolate-scope']>tbody>tr"));
  return  columnElements.size();
}

```
