我的表格有 tagName“td”和“mat-cell”。我已經實現了如下示例的源代碼，它只獲取具有 tagName 的單元格的值為“td”。如何獲取包含 tagName 為“td”或“mat-cell”的數據？WebElement 表 = driver.findElement(taskListTablexpath);    List<WebElement> rows = table.findElements(By.tagName("tr"));    int row_count = rows.size();    System.out.println("Total Row: " + row_count);    for (int row = 0; row < row_count; row = row + 2) {        **List<WebElement> columns = rows.get(row).findElements(By.tagName("td"));**        int columns_count = columns.size();        System.out.println("Number of cells In Row " + row + " are " + columns_count);        for (int column = 0; column < columns_count; column++) {            String celtext = columns.get(column).getText();            if (celtext == null)                continue;            System.out                    .println("Cell Value of row number " + row + " and column number " + column + " Is " + celtext);        }        System.out.println("-------------------------------------------------- ");    }}
