The PrimeNG TreeTable component provides a feature to enable flex scrolling for the rows of the table. Flex scrolling is a technique that allows a scroll bar to appear only for the rows, not for the whole table. This technique is useful when the number of columns in the table is large and the table becomes wider than the width of its container. To enable flex scrolling, the TreeTable component provides the scrollable property.

Here's an example of how to use scrollable property:

  
      
          Column 1
          Column 2
          ...
      
  
  
      
          {{rowData.col1}}
          {{rowData.col2}}
          ...
      
  

In this example, the scrollable property is set to true, which enables flex scrolling. The value property is bound to data to populate the tree table with data. The pTemplate directive is used to define the table header and body templates. The ttRow directive is used to mark each row for processing by the TreeTable component.

With flex scrolling enabled, the rows of the table will overflow horizontally and a scroll bar will appear only for the rows. The header of the table will remain fixed at the top of the table. This makes it easier to read the data in the table when the number of columns is large. 免责声明：本文内容通过AI工具匹配关键字智能整合而成，仅供参考，火山引擎不对内容的真实、准确或完整作任何形式的承诺。如有任何问题或意见，您可以通过联系service@volcengine.com进行反馈，火山引擎收到您的反馈后将及时答复和处理。
