How to make only one cell editable in smart table sapui5

I am using a sapui5 smart table to list down my products. It includes product code, product description and order quantity.

Among these three fields i want to update only the order quantity. It should be an inline editing in the table.

In my smart table i have enabled the property "editable" as "true". It makes the entire row is editable. Instead of making entire row editable, i want make only one cell to be editable.

Example

 <smartFilterBar:SmartFilterBar id="smartFilterBar" entityType="ZDEMO_C_MyEntityType" persistencyKey="SmartFilter_Explored">
 </smartFilterBar:SmartFilterBar>

 <smartTable:SmartTable id="mySmartTable" 
      smartFilterId="smartFilterBar"
      tableType="GridTable" 
      editable="true" 
      entitySet="ZDEMO_C_MyEntity" 
      useVariantManagement="false" 
      useTablePersonalisation="true" 
      header="My Products" 
      showRowCount="true" 
      useExportToExcel="true" 
      enableAutoBinding="true">
 </smartTable:SmartTable>

Solution

You can add a sap ui table inside the smart table and add columns with customdata property. Follow these steps.

Make editable="true" as editable="false"
In your xml, make sure to add this namespace xmlns:core="sap.ui.core"

Within the smarttable tag add below.

<smartTable:SmartTable .................................

         <Table>
            <columns>
                <Column>
                    <customData>
                        <core:CustomData key="p13nData" value='\{"columnKey": "OrderQty", "leadingProperty": "OrderQty", "columnIndex":"2"}'/>
                    </customData>
                    <Text text="Order Qty"/>
                </Column>

            </columns>
            <items>
                <ColumnListItem>
                    <cells>
                        <Input value="{OrderQty}" type="Number" editable="true"/>
                    </cells>
                </ColumnListItem>
            </items>
        </Table>

  </smartTable:SmartTable>
