Memory area in the node-red

I'm trying to create a memory area on node-red but I'm not succeeding. this would be to store read information of the modules being read by node-red.
is there a pallet for this application?

This would be the model of how you would present information on a dashboard.

Do you mean you want to display a table on the dashboard? If so then have a look at node-red-node-ui-table

Yes, I want to show it in a dashboard, but I also want to create this memory area on node-red.

For a memory area you can create a javascript object or an array in the node red context. This can be in persistent memory if necessary, if you need it to be saved over a node-red restart. Working with context : Node-RED
