Answer 1

You can select the rows for example by using CSS-selectors like :

#SlotTable > tr:nth-child(1)

#SlotTable > tr:nth-child(2)

Answer 2

元素的样式似乎相同，因此您可以将它们用作标识符并选择具有该特定样式的所有元素，然后对这些元素进行操作。

Answer 3

Try to get row using xpath:

//tbody[@id='tableBody']//tr[1]

//tbody[@id='tableBody']/script/tr[1]

Change number to access the row you need.

Answer 4

Put this method you will get list of all the ids of rows and you can perform all the activity after that using their id's :

public ArrayList<String> ListOfIdsOfRows()
{
   WebElement table =driver.findElement(By.id("SlotTable"));
   WebElement tbody=table.findElement(By.tagName("tbody"));
   List<WebElement> rows=tbody.findElements(By.tagName("tr"));
   ArrayList<String> ListOdIds=new ArrayList<>();

   for(int i=0;i<rows.size();i++)
   {
     WebElement row = tbody.findElement(By.xpath("//table[@id='SlotTable']/tbody/tr["+(i+1)+"]"));
     String rowId=row.getAttribute("id");
     ListOdIds.add(rowId);
   }

   return ListOdIds;
}
