Hi, I have unexpected results with the following code in a function node. I have a table node behind this function node, but the table only updates when I refresh the browser, so the data is getting there in the correct format, but for some reason, the table is not updating when new data arrives.

Any help would be greatly appreciated.

```auto
var distanceFromBle = Math.pow(10, (-54 - (msg.payload.brssi)) / (10 * 3.5)).toFixed(1);

tableData = flow.get("savedData") || [];

tableData.unshift({
    "bmac" : msg.payload.bmac,
    "apmac": msg.payload.apmac,
    "mymac": msg.payload.mymac,
    "ltime": msg.payload.ltime,
    "wrssi": msg.payload.wrssi,
    "brssi": msg.payload.brssi,
    "distance": distanceFromBle
});

if (tableData.length > 9) tableData.pop();

msg.payload = tableData;

flow.set("savedData", tableData);

return msg;

```

I believe the issue is when you try to add a row, best use the command function addRow , there is info in the help text, there are also example flows in the import examples.

here is an example, i have hardcoded the incoming values, so you will need to edit

```auto
