I need to create a functionality as follows

  1. render list into editable data grid
  2. Under each column, need to display sum values, if they are integers

You can render a ListModel with zk grid in MVVM pattern, please refer to http://books.zkoss.org/zk-mvvm-book/8.0/databinding/collectionand_selection.html

To listen to values change, you can render a <intbox>/<decimalbox> in a row and specify a command binding at onChange event:

<intbox onChange="@command('update')"/>

In that method, you can update the sum of the corresponding column.

If you want more powerful formula features, please use Keiaki.

If you still encounter problems, please describe specific and technical details.
