Hello, I have a node-red-node-ui-table set up. I am confused because all of the examples simply use an inject node to inject data. I am reading data from an OPCUA server from a PLC. I am trying to log machine "feeds" into the table so it would display User, Time, and Pounds. Below is my flow...

with commands offer the hole flexibilty of tabulator. The table can be manipulated down to cell level.\nAs the ui-table node only passes the commands to tabulator and receives promises back the node does not hold the table data. If the data should be available after refresh, tab change, new connections the flow is responsible to cache the data and all the manipulations.\nThis node takes care of most simple data manipulation commands and holds a copy of the data in `flow.context.tabledata`\n\n## details\n\n### row index (id)\n\nTo identify a [row a index](http://tabulator.info/docs/4.5/data#overview) column has to be defined. This colum defaults to `id` but can be changed by specifing a **field** by using `msg.ui_control`. In this example the row index is a simple counter adding up by one if a new line is added.\n\n### addRow command\n\n[details @ tabulator addRow docs](http://tabulator.info/docs/4.5/update#alter-add)\n\nYou can add a row by sending the `addRow` command. You can decide if the row adds on the top or at the bottom of table.\n\n### addOrUpdate command\n\n[details @ tabulator addOrUpdate docs](http://tabulator.info/docs/4.5/update#alter-update)\n\nTo update data the best way is to use the `addOrUpdate` command. If the row indetified by the index is not exeisting a new row will be added automatically\n\n### deleteRow command\n\n[details @ tabulator deleteRow docs](http://tabulator.info/docs/4.5/update#row)\n\nDelete one or more rows (passing an array always results in \"row not found error\"! I think there is an issue in tabulator)\n\n### clearData\n\n[details @ tabulator clearData docs](http://tabulator.info/docs/4.5/update#alter-empty)\n\nunfortunately this command (currently) do not send a promise back!
