Hi,

I am trying to add a filter to the entire table similar to Viewers{i.e. by using ViewerFilter}.I went through all the examples and the NatTable forum, looking for examples related to filtering but I could only find information related to column filters.
Could you please suggest how I can achieve this in NatTable?

Regards,
KiranKumar H.V

Sorry I don't understand your requirement. What do you mean with "add a filter to the entire table"? If there should be only one field that performs a filter operation you will need to create an external control and apply a filter. Within NatTable you could try to create a cell that spans all other cells. Not sure if that breaks any other use case for huge data sets.

If you just need to set a filter in the background instead of having a filter row, than you should look either on how to filter with a FilterList in GlazedLists (if you are using GlazedLists) or as an alternative have a look at AbstractFilterListDataProvider. Although I suggest to use the FilterList approach, because the AbstractFilterListDataProvider is not the best when it comes to performance. So for huge datasets it will be a mess.

Thanks for the quick reply dirk,

Yes i wanted to have a filters like Treeviewer.addFilter(new ViewerFIlter());
during refresh these filters were apllied in normal viewers.
I wanted to contribute a feature similar to these in natTable so that i can plug any filters at runtime.

As you said, i looked in to FilterList and implemented my own filter stratergy for filtering. It worked. Smile

Now i have to make it somewhat generic so that i can add as many filters for background Processing Smile

Regards,
Kiran
