Updation of a table by taking data from a input box

[#1]

Consider a scenario that I have a table box with two columns,

1. Author name

2. Report _id

Assume that some of the author names are missed.

Is there any chance in UI that I can select the report id which is missing the author and If I type a author name in a input box and press a

button , can It be updated in the table box.

If it is possible can I do the same back into the database table from where I have loaded this table.

I have attached a word document just to get an idea of What I want.

Thank You.
