Manipulate icon properties for the last row of table

问题

In XML view for i have :

<Table id="testtable" xmlns="sap.ui.table"
  rows="{/testdata}"
  alternateRowColors="true">
  <columns>
    <Column hAlign="Center" label="Col1">
      <template>
        <m:Text text="{dataX}" wrapping="false" />
      </template>
    </Column>
    <Column hAlign="Center" label="Col2">
      <template>
        <m:Text text="{dataY}" wrapping="false" />
      </template>
    </Column>
    <Column label="Col3">
      <template>
        <m:HBox>
<core:Icon src="sap-icon://show" color="{ parts : [ 'test'], formatter: '.setIconColour'}" />
<core:Icon src="sap-icon://edit" color="{ parts : [ 'test' ], formatter: '.setIconColour'}" />
<core:Icon src="sap-icon://print" color="{ parts : [ 'test' ], formatter: '.setIconColour'}" />
        </m:HBox>
      </template>
    </Column>
  </columns>
</Table>

In controller (formatter function is as):

setIconColour: function (value) {
 if (value === 1) {
    return "#007bff";
  } else if (value === 2) {
    return "Positive";
  } else if (value === 3) {
    return "Negative";
  } 
}

The sample data is as:

{"testdata": [
    { "dataX": 1, "dataY": "testdata", "test": 0},
    { "dataX": 2, "dataY": "testdata", "test": 2},
    { "dataX": 3, "dataY": "testdata", "test": 3},
    { "dataX": 4, "dataY": "testdata", "test": 1}
]}

This changes color of Icon Properties based on test value ,after this may i know how can i change the color of only last row icons or (only row) if only one row exists (rest all have same properties as per formatter function)

I am trying to do this as :

      var tabItems = this.byId("testtable").getRows(); 

      var cells = tabItems[testdata.length-1].getCells(); // get last row cells

      cells[8].mAggregations.items[0].setColor(
      "#000000");  // at this path i have all 3 icons and trying to set color here (items[0],items[1],items[2] --> 3 icons)

But this approach doesn't work as expected giving weird results until page refresh , hope there would be a better way , any help or guiding links are much appreciated TIA

Maybe you can add index your JSON then you can give index and length of JSON to your formatter.

JSON like this:

{"testdata": [
    { index: 1, "dataX": 1, "dataY": "testdata", "test": 0},
    { index: 2, "dataX": 2, "dataY": "testdata", "test": 2},
    { index: 3, "dataX": 3, "dataY": "testdata", "test": 3},
    { index: 4, "dataX": 4, "dataY": "testdata", "test": 1}
]}

Formatter:

setIconColour: function (value, index, length) {
 // 
}
