title: UI5 ui.table combobox (combobox located in table row) with list items filtered by value in another column
body: <p>I so appreciate thoughts and suggestions on how to do this Binding.
  This could be very useful, to others, if we can make this work!  :)</p>

  <a href="https://i.stack.imgur.com/szQFX.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/szQFX.png" alt="Combox (row 3) item list should only contain 3 items equal to value key in Col1" /></a></p>
  <hr />
  <pre><code>Only the 3 circled items should be displayed in the row 3 combobox. *(see screen shot above)*
  </code></pre>
  <p>Each combo box should have a custom list of items, filterd by value in Col1. <em>(see screen shot above)</em></p>
  <p>Currently combobox displays too many values;  all values available for all table rows.</p>
  <p>The combobox data/model has a key value related to the value in Col1.  <em>(See Sample Data below)</em></p>
  <p>Should I create a model for each key/value group; I'm not sure?</p>
  <p>Currently I am un-able to reference the Table's many combobox clones (one for each row in the table).</p>
  <pre><code>Not sure if do/don't need attribute 'templateShareable:false/true'?
  </code></pre>
  <p>The Table model and Combobox model load via a manifest.json dataSource.</p>
  <p>manifest.json entry:</p>
  <pre><code>&quot;sap.ui5&quot;: {
      &quot;models&quot;: {
          &quot;&quot;: {
              &quot;dataSource&quot;: &quot;Main&quot;,
              &quot;type&quot;: &quot;sap.ui.model.json.JSONModel&quot;
          },
  </code></pre>
  <p>XMLView for Table:</p>
  <pre><code>    &lt;Table id=&quot;Table1&quot;
          rows=&quot;{/Rowsets/Rowset/0/Row}&quot;
  </code></pre>
  <p>XMLView for Column and combobox:</p>
  <pre><code>&lt;Column&gt;&lt;m:Label text=&quot;Col2&quot;/&gt;&lt;template&gt;
      &lt;m:ComboBox id=&quot;cb1&quot; items=&quot;{path: '/Rowsets/Rowset/1/Row', templateShareable:false}&quot;
                  change=&quot;handleInterBatch&quot;
                  showSecondaryValues=&quot;true&quot; 
                  filterSecondaryValues=&quot;true&quot; 
                  value=&quot;{Batch}&quot;
                  placeholder=&quot;Select...&quot;
                  &gt;&lt;core:ListItem key=&quot;{Batch}&quot; text=&quot;{Batch}&quot; additionalText=&quot;{Catalog}&quot;/&gt;
      &lt;/m:ComboBox&gt;&lt;/template&gt;&lt;/Column&gt;
  </code></pre>
  <p><em>(See Sample Data below)</em></p>
  <pre><code>Sample Data /Rowset/0/Row populates the Table.
  Sample Data /Rowset/1/Row populates the Combobox.
  </code></pre>
  <p>Sample Data:</p>
  <pre><code>{ &quot;Rowsets&quot; : {
      &quot;Rowset&quot; : [ 
      {   &quot;Row&quot; : [
