Example: Adding Columns to a Responsive Table on the Object Page

You have to implement two extension points to add a custom column to a table.

Context

Caution:

Use app extensions with caution and only if you cannot produce the required behavior by other means, such as manifest settings or annotations. To correctly integrate your app extension coding with SAP Fiori elements, use only the extensionAPI of SAP Fiori elements. For more information, see Using the extensionAPI.

After you've created an app extension, its display (for example, control placement and layout) and system behavior (for example, model and binding usage, busy handling) lies within the application's responsibility. SAP Fiori elements provides support only for the official extensionAPI functions. Don't access or manipulate controls, properties, models, or other internal objects created by the SAP Fiori elements framework.

Custom columns in a responsive table on the object page

Procedure

  1. Define a fragment for the view extension.

    For a custom column in a responsive table, you have to implement two extensions. First, implement the definition of the custom columns and then implement the content of the custom columns.

    In the example project: webapp/ext/fragments/ProductTextResponsiveTableColumns.fragment.xml:

    Sample Code:

    <core:FragmentDefinition xmlns:core="sap.ui.core"
       xmlns="sap.m">
       <Column>
              <Text text="{i18n|sap.suite.ui.generic.template.ObjectPage|STTA_C_MP_Product>xfld.BreakoutColumn}" />
              <customData>
                     <core:CustomData key="p13nData"
                            value='\{"columnKey": "Test", "columnIndex" : "101"}' />
              </customData>
       </Column>
</core:FragmentDefinition>

    In the example project: ProductTextResponsiveTableCells.fragment.xml:

    Sample Code:

    <core:FragmentDefinition xmlns:core="sap.ui.core" xmlns="sap.m">
       <Text text="{i18n|sap.suite.ui.generic.template.ObjectPage|STTA_C_MP_Product>xfld.BreakoutColumnContent}"></Text>
</core:FragmentDefinition>

  2. Register your view extensions in the manifest.json file of your application as follows:

    For information on naming, see Extension Points for Tables.

    Sample Code:

    ...
 "extends": {
      "component": "sap.suite.ui.generic.template.ListReport",
      "minVersion": "1.1.0",
      "extensions": {
        "sap.ui.viewExtensions": {
"sap.suite.ui.generic.template.ObjectPage.view.Details": {
            "ResponsiveTableColumnsExtension|STTA_C_MP_ProductText|to_ProductText::com.sap.vocabularies.UI.v1.LineItem": {
                  "className": "sap.ui.core.Fragment",
                  "fragmentName": "STTA_MP.ext.fragments.ProductTextResponsiveTableColumns",
                  "type": "XML"
            },
            "ResponsiveTableCellsExtension|STTA_C_MP_ProductText|to_ProductText::com.sap.vocabularies.UI.v1.LineItem": {
                  "className": "sap.ui.core.Fragment",
                  "fragmentName": "STTA_MP.ext.fragments.ProductTextResponsiveTableCells",
                  "type": "XML"
            }    
      },
