Table input field.

I have to create a table which will take input from user. I have created the context and binded it to the table. At the time of biniding with table i mentioned that these will be input field. But the problem is as the node has no value the table becomes uneditable.I have to give user 5 rows for editing. Can any one tell me the steps of creating this.

<b>If possible please provide the detail step & Sample code.
