Good morning, I would like to generate a table in an automatic way. For that I would like to write an script that generates the bindings of the table to map different cells with Tags. Is there any way to do that? I dont want to spend 4 days adding tags to the table. Thanks in advance ---

The table component is not ideal for this. Usually we want the table to update if the `data` changes. This can happen automatically if a binding is applied to the `data` property _if_ the tag is referenced in the binding. The binding is added to a subscription to that tag and any time the tag changes the binding re-evaluates. (Referencing it in a binding transform doesn't do this, so a script transform won't subscribe.) Explain some more how you want this to work. ---

I want to display on a table the GPS position of different vehicles, this GPS (latitude and longitude) are tags in the tag browser. But I have more than 100 hundred vehicles. So I would like to automate the binding generation to the DATA property of the table. ---

OK, so you could create an expression binding with `now(30000)` (which will trigger every 30 s) and write a script transform on that to create the data. Is this what you have in mind? Why not [Perspective - Map | Ignition User Manual](https://www.docs.inductiveautomation.com/docs/8.1/appendix/components/perspective-components/perspective-display-palette/perspective-map) instead of a table? It would make a lot more sense. ---

Thanks a lot! great idea, works fine. The map is good if you want to display on a map, but this is not the case, we need it in a table format. Deeply appreciate your tip!! ---

Good - although I can't imagine what use a table of grid coordinates is, unless you're launching missiles at them. ---

Be aware that if you repeatedly regenerate a Perspective Table's `props.data` in this manner, the table will be extremely annoying for the user, because any row selections or paging will be lost when the binding updates. Make the table have a column for the static tag paths to the coordinate tags. Set those columns to use "view" render mode, and point the cells at a nestable view that can indirect bind to the tag for the dynamic display. ---

Amazing, thanks for the consideration! works great!
