Hallo Deepika,
If you would like to do enable/disable a row in a table then you have to bind the columns to context attribute of type wdy_boolean.
you can do that in two ways..(or more)
1. Introduce new singleton node (Say UI_PROP) with cardinality 1..1 inside your table context node.
   add a attribute row_readonly of type wdy_boolean.
bind this attribute to the columns of your rows read_only property.
when you select a row and press a change button, code in the event handler that the UI_PROP ->row_readonly to abap_true.
2. You can bind the read only property of the cell-editor with the the attribute property of the column. In this way you do not have to introduce new node and attribute as mentioned in first option.
      lo_el_tabnode->set_attribute_property(
       attribute_name = `Attribute name`
       property =  lo_el_tabnode->e_property-read_only
       value     = abap_true ).
Regarding Insert.
You can add a new context element to the node at index 0. This way you can get the insert at first row.
