asp.net - Are there any simple javascript spreadsheet widgets? -

I have to create a simple web-based expense calculator. We are using asp.net web forms, and each cell will be a text box. The goal is to continue each value (but the total) in a database - so I have an expense table and an expense_day table with the values ​​of each row in the text box.

There will be a week's worth of rows and 6-8 columns. Each call must be completed in the form of each column.

Is there a simple JavaScript framework that will do this? We are already using jquery, but I do not include any other special special library if it will make this feature easier.

Update:

Also the overall column will be ideal.

Take a look at this

It seems as if it was using Thimolor That is very clean, which is very clean.
