Grid with often updated column

Hello. I have a Grid with about 40 columns and 20-100 rows in different times.
Updates are about 5 seconds. Some components in Grid can send click-events to server, and there is some trouble occured when i click on components in Grid-update period. Some events are lost. How can i update only one column in grid? I want to save app traffic and UI responsibility. Create new [issue]

P.S. Over year ago i was [asking]
( about similar feature too, but for Vaadin Framework at that time.
