所有可排序列上的GWT CellTable排序箭头图标

[英]GWT CellTable Sort arow Icon on all sortable columns

I'm having a CellTable with sortable Columns and it works like in the showcase ( GWT CellTable showcase ). 我有一个带有可排序列的CellTable ,它的工作方式类似于展示柜( GWT CellTable展示柜 )。 But I think this is not very user friendly. 但是我认为这不是非常用户友好。 Because the sort arrow icon is only on 1 column and I think it should be an all (set to be) sortable columns. 因为排序箭头图标仅在1列上,所以我认为它应该是所有(设置为)可排序的列。 How can I have a arrow icon, with the same behavior, over all sortable columns. 如何在所有可排序的列上使用具有相同行为的箭头图标。 thanks for any help :) 谢谢你的帮助 :)

An arrow shows which column is currently sorted. 箭头显示当前正在排序的列。 If you put arrows on all columns, how will a user tell which column is currently used for sorting? 如果将箭头放在所有列上,用户将如何得知当前用于排序的列? I think it defeats the purpose of the arrow. 我认为它违反了箭的目的。
