We removed APIs from TLC components that are available in PresentationModels to avoid duplicating APIs and add extra size.
This is an example from Tour De Jewel that uses rowHeigh` in DataGridPresentationModel:
<j:DataGrid localId="dg4" height="205"
change="dataGridChange(event.target as DataGrid, lb4)"
dataProvider="{productModel.productList}">
<j:columns>
<j:DataGridColumn label="Images" dataField="image" columnWidth="100"
itemRenderer="itemRenderers.ImageDataGridItemRenderer"/>
<j:DataGridColumn label="Title" dataField="title" columnWidth="140"/>
<j:DataGridColumn label="Sales" dataField="sales" columnWidth="80" align="right"/>
</j:columns>
<j:beads>
<j:DataGridPresentationModel rowHeight="54"/>
</j:beads>
</j:DataGrid>
