Answer 1

It's very simple.
1) Import your RFC.
For this:
-Right click on Models->Create Model->Select Import Adaptaive RFC then follow the steps.
-Go to Used Models. Right click -> Add... -> then select the model that you created.
2) I guess you have a view that is using a controller (Custom/Component) so:
-Go to Context Tab-
-Create a model node.
-Bind the model node with the model that you created.
-Go to the view where you want to put the Table ui element and add the table (Outline window->right click->Insert Child->Table)
-Go to context tab, add a model node, en map it (Edit context mapping) with the model node that you created in the controller.
-Go back to layout tab. Then in table properties, in datasource click on the "..." and select the output node of the model that you have created in the view.
-Then in Outline Window-> Right click on the table element-> Create binding-> check the attributes that you want to be binded to the table.
-Then follow the steps.
You have now your table binded to the rfc.
Finally what you have to do is to create a method to execute the rfc. Usually it is written in the controller. Something like this:
public void execute<YourBapiName>( )
    //@@begin execute<YourBapiName>()
     IWDMessageManager manager = wdComponentAPI.getMessageManager();
     try
       wdContext.current<YourBapiName>Element().modelObject().execute();
       wdContext.node<YourBapiOutputNode>().invalidate();
       wdContext.current<YourBapiName>Element().modelObject().modelInstance().disconnectIfAlive();
     catch(WDDynamicRFCExecuteException e)
       manager.reportException(e.getMessage(), false);
    //@@end
To call this method, first, you have to bind the input parameters and then execute it (you can do this wherever you want):
<YourBapiName> input = new <YourBapiName>();
input.set<YourBapiParameters>(<YourParameter>);
wdContext.current<YourBapiName>Element.bind(input);
wdThis.wdGet<YourControllerName>(Controller().execute <YourBapiName>();
I hope it helps.
Bye bye.
