Hi,
For example you have one table in your view and you want to apply the filter for that table.
And the node binded to that table is TestNode with two attributes Att1 and Att2 with cardinality 0..n & selection 0..1.
You need to create two more nodes with the same attributes in the context:
1. FilterTestNode Having same attributes Att1 & Att2 and with cardinality: 1..1 & selection 0..1
2. SourceTestNode Having same attributes Att1 & Att2 and with cardinality 0..n & selection 0...1.
Note: Everytime when you are populating the data into TestNode you should populate the same data into SourceTestNode also.
Create one context attribute "TableFilter" directly under Root context as below:
Change the type of the "TableFilter" attribute to java class TableFilter.
Go to the properties of the  table columns: Bind the Attr1 of FilterTestNode to FilterValue property of the Column1 and Bind the Attr2 of FilterTestNode to FilterValue property of the Column2.
In the actions tab create one action as "Filter" and write the below code in that action:
wdContext.currentContextElement().getTableFilter().filter(wdContext.nodeSourceTestNode(),wdContext.nodeTestNode());
In wdDoModifyView() method write the below code:
if (firstTime) {
//Here in the below line of code, "Table" is the ID of the UI element table.
IWDTable tableFilter = (IWDTable) view.getElement("Table");
wdContext.currentContextElement().setTableFilter( new TableFilter(tableFilter, wdThis.wdGetFilterAction(), wdContext.nodeSourceTestNode(), null));
