Hi,
For this u have to fetch the selected row.
For fetching the selected row go to the events of first table and select "OnLeadselect".
Create a new method for this.
Now in this method read the value of the selected row with method get_static_attributes.
with this u will have the selected row in the element.
not just bind this elemnt with the second table.
Second node will also have the cardinality 0:n, because this is also binded with the table.
Coding part for this is as below:
method ONACTIONSELECT .
    DATA lo_nd_cn_mara TYPE REF TO if_wd_context_node.
    DATA lo_el_cn_mara TYPE REF TO if_wd_context_element.
    DATA ls_cn_mara TYPE wd_this->element_cn_mara.
    DATA ls_cn_mara1 TYPE wd_this->elements_cn_mara.
  navigate from <CONTEXT> to <CN_MARA> via lead selection
    lo_nd_cn_mara = wd_context->get_child_node( name = wd_this->wdctx_cn_mara ).
  @TODO handle not set lead selection
    IF lo_nd_cn_mara IS INITIAL.
    ENDIF.
  get element via lead selection
    lo_el_cn_mara = lo_nd_cn_mara->get_element(  ).
  @TODO handle not set lead selection
    IF lo_el_cn_mara IS INITIAL.
    ENDIF.
  alternative access  via index
  lo_el_cn_mara = lo_nd_cn_mara->get_element( index = 1 ).
  @TODO handle non existant child
  IF lo_el_cn_mara IS INITIAL.
  ENDIF.
  get all declared attributes
    lo_el_cn_mara->get_static_attributes(
      IMPORTING
        static_attributes = ls_cn_mara ).       " here u are getting the selected row of the table.
APPEND ls_cn_mara to ls_cn_mara1.      " append the row in the table so that can be binded with the second node
  DATA lo_nd_cn_maraout TYPE REF TO if_wd_context_node.
  DATA lo_el_cn_maraout TYPE REF TO if_wd_context_element.
  DATA ls_cn_maraout TYPE wd_this->element_cn_maraout.
navigate from <CONTEXT> to <CN_MARAOUT> via lead selection
  lo_nd_cn_maraout = wd_context->get_child_node( name = wd_this->wdctx_cn_maraout ).
Bind the table with the second node
lo_nd_cn_maraout->bind_table( ls_cn_mara1 ).
endmethod.
->cn_mara  is the first node.
->cn_mara1  is the second node
