This hook is called before rendering a child-object table on the detail page.

Parameters

functional registers the hook callback. The host passes the following parameters:

Parameter	Description	Type	Allowed Values	Default
context	Event context containing common parameters	Object	--	--
plugin	Current plugin runtime information; business logic normally does not need it	Object	--	--
context.targetObjectApiName	API name of the child object	String	--	--

Return Value

The hook may return a configuration object or Promise<Object>.

Parameter	Description	Type	Default
columnsExtendConfig	Column extension configuration	Object	--
termExtendConfig	Scenario extension configuration	Object	--
viewInfoExtendConfig	View extension configuration	Object	--
actionExtendConfig	Button behavior extension	Object	--
formatListDataAsync	Processes current-page List API data	Function	--
formatRequestParam	Processes List API request parameters	Function	--
forceTrWrap	Whether cells forcibly wrap	Boolean	--
buttons	Toolbar button configuration	Object	--
operateBtns	Row action extension functions	Function[]	--

columnsExtendConfig

Parameter	Description	Type	Default
filterColumns	Fields hidden from the table, table settings, and filters	Array	--
render	Custom cell render functions	Object	--
attrs	Cell attribute extensions	Object	--

columnsExtendConfig.render

The render function signature is render(value, type, data, index). The host uses it directly as the table column render function.

Parameter	Description	Type
value	Raw field value before default formatting	Any
type	Normally column; some partial updates pass the current column object	String | Object
data	Complete row data	Object
index	Row index within the current page	Number

Returned strings are rendered as cell HTML. Escape raw values before including them in HTML.

columnsExtendConfig.attrs

An attrs key may be a field API name, returnType, or dataType. A field API name takes precedence.

Parameter	Description	Type	Default
showLookupText	Shows lookup text without a link	Boolean	--
isEdit	Enables cell editing	Boolean	--
noSupportBatchEdit	Disables batch editing	Boolean	--
disabledDel	Disables clearing the field value	Boolean	--
fixed	Fixes the column to the left	Boolean	--

termExtendConfig and viewInfoExtendConfig

termExtendConfig.default is the default scenario API name, and termExtendConfig.retain contains scenario API names or IDs to retain. viewInfoExtendConfig.default selects the default view.

actionExtendConfig

Keys are case-sensitive runtime actions. parseParam(params) returns properties shallow-merged into button execution parameters. beforeRowAction(params) must return a Promise; resolution continues the default action and rejection stops it.

formatListDataAsync

formatListDataAsync(listData) receives { totalCount, data } and must preserve that structure. It may return an object or Promise<Object>.

formatRequestParam

formatRequestParam(params) receives complete List API request parameters. Return an object to shallow-merge changes, or mutate params and return nothing.

buttons

buttons supports add, del, and reset. An added button requires action and label; use callback(), exposed, and placement: { base, relative } as needed. child-table toolbar callbacks receive no arguments; read record or object information from the enclosing hook context.

operateBtns

operateBtns is an array of (rowData) => ({ add, del, reset, retain }) functions. Custom row buttons require action, label, and callback(params). The callback receives the complete row-action parameters.

Basic Examples

Hide a Column

return Promise.resolve({
    columnsExtendConfig: {
        filterColumns: ['name']
    }
});

Customize Cell Content

return Promise.resolve({
    columnsExtendConfig: {
        render: {
            owner: (value, type, data, index) => 'Hello'
        }
    }
});

Set the Default Scenario

return Promise.resolve({
    termExtendConfig: {
        default: 'All',
        retain: ['All', 'InCharge']
    }
});

Extend Button Parameters

return Promise.resolve({
    actionExtendConfig: {
        add: {
            parseParam: () => ({
                record_type: 'default__c',
                success() {
                    context.bizApi.refresh();
                }
            })
        }
    }
});

Extend List Request Parameters

return Promise.resolve({
    formatRequestParam(params) {
        const searchQueryInfo = JSON.parse(params.search_query_info);
        searchQueryInfo.filters = searchQueryInfo.filters || [];
        searchQueryInfo.filters.push({
            field_name: 'name',
            field_values: ['value'],
            operator: 'LIKE'
        });
        return {
            search_query_info: JSON.stringify(searchQueryInfo)
        };
    }
});

Add a Toolbar Button

return Promise.resolve({
    buttons: {
        add: [{
            action: 'cancel',
            label: 'Cancel',
            callback() {
                console.log(context.objectApiName);
            }
        }]
    }
});

Add a Row Action

return Promise.resolve({
    operateBtns: [
        rowData => ({
            add: [{
                action: 'customRowAction',
                label: 'Custom Row Action',
                callback(params) {
                    console.log(rowData, params.data);
                }
            }]
        })
    ]
});

FAQ

Q: Why does the next page fail to update when formatListDataAsync changes request parameters?

A: formatListDataAsync processes current-page response data. Use formatRequestParam to change limit, offset, or other request parameters.
