Unique values for DataGrid Components

[Seth-Know]

My goal is to a have textfield within a datagrid that is unique. Each row with this same textfield should also be unique. I have tried using JSON Logic a couple different ways, but I am not getting the expected result.

My goal is to have something similar to this:

My results now with JSON Logic:

JSON (w/ JSON Logic used) :

{ "display": "form", "components": [ { "label": "Data Grid", "reorder": false, "addAnotherPosition": "bottom", "layoutFixed": false, "enableRowGroups": false, "initEmpty": false, "tableView": false, "defaultValue": [ { "myField": "" }, { "myField": "" } ], "key": "dataGrid", "type": "datagrid", "input": true, "components": [ { "label": "Text Field", "tableView": true, "validate": { "json": { "if": [ { "some": [ { "var": "data.dataGrid" }, { "!==": [ { "var": "item.myField" }, { "var": "input" } ] } ] }, true, "Value already exists in datagrid" ] } }, "key": "myField", "type": "textfield", "input": true }, { "label": "Text Field", "tableView": true, "key": "textField", "type": "textfield", "input": true } ] } ] }

I also tried setting "unique" : true, however is doesn't work for my case or I am simply using it wrong. Still a novice and learning. I appreciate any help or experience anyone can share.
