EXAMPLE (template) - displaying a one dimensional table

Problem: You need to display a table of temperatures.

Sample data (temperatures): 67.4, 69.5, 72.5, 67.8, 65.0

We will use a function node to create the table using:

var arr =[67.4, 69.5, 72.5, 67.8, 65.0];
msg.payload = arr;
return msg;

In real life you probably have a sensor generating the data.

Next, we will display the table using the template node. Here is what we use in the template node:

<table id="table" border="1">
    <tr>
        <th>Temperature</th> 
    </tr>
    <tbody>
        <tr ng-repeat="row in msg.payload">
            <td class="numeric" >{{row}}</td>
        </tr>
    </tbody>
</table>

Notice that the TR element has a ng-repeat option that is the key to displaying all rows of the table.

Here is what the display will look like:

Temperature
67.4
69.5
72.5
67.8
65.0

the following is the flow that is used in this example:
