Good day,

I am reading a lot of posts about how to write to a tag from a perspective table but have not found a solution for what I am trying to do.

I would like to use a perspective table as an input for multiple indirect tags bound to each data prop element. I am not binding to the entire data prop, but instead items in each array:

I have tried using the following:

```auto
def runAction(self, event):
	valueToSet = event.value
	self.props.data[event.row]['value'][event.column] = valueToSet

```

and get the following error:

```auto
Error running action 'component.onEditCellCommit' on 9 Press KY/AgingOvenLoad@D/root/Table: Traceback (most recent call last): File "<function:runAction>", line 3, in runAction KeyError: value

```

Is this possible to do with a perspective table or am I going down a dark hole. Once this is setup, there will be a set amount of data points and the entire dataset will not change in size. Thanks!

Make sure cells are set to be editable under your `columns` property, then under `onEditCellCommit` event, use

```auto
self.props.data[event.row][event.column] = event.value

```

Thank you worked like a charm.
