The table node displays data in a tabular format with advanced features. Supports sorting, filtering, pagination, row selection, and auto-updating. Perfect for displaying sensor logs, device lists, and structured data.

Properties

Input Format

// Array of objects
msg.payload = [
  { id: 1, device: "Sensor-01", temperature: 24.5, status: "active" },
  { id: 2, device: "Sensor-02", temperature: 22.1, status: "active" },
  { id: 3, device: "Sensor-03", temperature: 28.7, status: "warning" },
  { id: 4, device: "Sensor-04", temperature: 19.3, status: "inactive" }
];

// Table auto-creates columns: id, device, temperature, status

Custom Column Configuration

  "payload": {
    "id": 2,
    "device": "Sensor-02",
    "temperature": 22.1,
    "status": "active"
  }
}

// Use selected row for actions:
// → View details
// → Delete device
// → Edit configuration

Append & Update Rows

// Add single row to end
msg.payload = {
  id: 5,
  device: "New Sensor",
  temperature: 25.0
};
// Table appends row

// Replace entire table
msg.payload = [
  { id: 1, ... },
  { id: 2, ... }
];
// Table replaces all rows
