I am using angular slickgrid for showing my data. When I am trying to edit the slick grid record, I will get the changed fields only I need the entire object. I have given the sample data.
Columndefinition :

this.columnDefinitions = [
      {
        id: 'title', name: 'Title', field: 'title', width: 220, cssClass: 'cell-title',
        filterable: true, sortable: true,
        queryFieldSorter: 'id', type: FieldType.string,
        formatter: Formatters.tree,
        editor: {
          model: Editors.longText,
          required: true,
        },
      },
      { id: 'duration', name: 'Duration', field: 'duration', minWidth: 90, filterable: true },
      {
        id: 'child.0.percentComplete', name: '% Complete', field: 'child.0.percentComplete', minWidth: 120, maxWidth: 200,
        sortable: true, filterable: true, filter: { model: Filters.slider, operator: '>=' },
        formatter: Formatters.percentCompleteBar, type: FieldType.number,
        editor: {
          model: Editors.slider,
          minValue: 0,
          maxValue: 100,
          params: { hideSliderNumber: false },
        },
      },

    ];

SlickGrid input data set structure:

const data = [
      {
        'id': 0,
        'indent': 0,
        'parentId': null,
        'title': 'Task 0',
        'duration': '5 days',
        'percentComplete': 73,
        'start': '2003-03-21T18:30:00.000Z',
        'finish': '2003-04-21T18:30:00.000Z',
        'effortDriven': true,
        'child' : [{
            'id': 2,
            'indent': 0,
            'parentId': 1,
            'title': 'Task 0',
            'duration': '5 days',
            'percentComplete': 73,
            'start': '2003-03-21T18:30:00.000Z',
            'finish': '2003-04-21T18:30:00.000Z',
            'effortDriven': true
        }]
      },
      {
        'id': 1,
        'indent': 0,
        'parentId': null,
        'title': 'Task 1',
        'duration': '5 days',
        'percentComplete': 4,
        'start': '2004-04-24T18:30:00.000Z',
        'finish': '2004-05-24T18:30:00.000Z',
        'effortDriven': false
      }
    ];

When I start to change the employee field oncellchanged called and I got arg.Item

Current behaviour

onCellChanged(e, args) {
    this.angularGrid.gridService.updateItemById(args.item['id'], args.item);
    console.log(args.item);
}

Log

{
  "id": 0,
  "indent": 0,
  "parentId": null,
  "title": "Task 0",
  "duration": "5 days",
  "percentComplete": 73,
  "start": "2003-03-21T18:30:00.000Z",
  "finish": "2003-04-21T18:30:00.000Z",
  "effortDriven": true,
  "child": {
    "0": {
      "percentComplete": 25
    }
  }
}

Expected output:

{
  "id": 0,
  "indent": 0,
  "parentId": null,
  "title": "Task 0",
  "duration": "5 days",
  "percentComplete": 73,
  "start": "2003-03-21T18:30:00.000Z",
  "finish": "2003-04-21T18:30:00.000Z",
  "effortDriven": true,
  "child": [
    {
      "id": 2,
      "indent": 0,
      "parentId": 1,
      "title": "Task 0",
      "duration": "5 days",
      "percentComplete": 25,
      "start": "2003-03-21T18:30:00.000Z",
      "finish": "2003-04-21T18:30:00.000Z",
      "effortDriven": true
    }
  ]
}

这个问题是由于Angular slickgrid库中使用的utils文件造成的。如果你想解决这个问题，有两个解决方案。
1.库本身处理函数逻辑。
1.需要根据您的要求实现自定义编辑器。
问题区域
在每个编辑器中，applyValue方法将对象值设置为各自的路径。在该方法中，数组值没有被正确解析。您可以扩展编辑器类并覆盖applyValue方法。这里我分享了示例代码供您参考。特别是，请仔细阅读我在下面提到的setDeepValue方法。

import { EditorArguments, InputEditor } from 'angular-slickgrid';

export class CustomInputEditor extends InputEditor {
  constructor(protected readonly args: EditorArguments, inputType: string) {
    super(args, inputType);
  }
  applyValue(item: any, state: any) {
    const fieldName = this.columnDef && this.columnDef.field;
    if (fieldName !== undefined) {
      const isComplexObject = fieldName?.indexOf('.') > 0; // is the field a complex object, "address.streetNumber"
    // is the field a complex object having array value you need to specify the index position in path (Here I used 0th index), "address.0.streetNumber"

      // validate the value before applying it (if not valid we'll set an empty string)
      const validation = this.validate(state);
      const newValue = validation?.valid ? state : '';

      // set the new value to the item datacontext
      if (isComplexObject) {
        // when it's a complex object, user could override the object path (where the editable object is located)
        // else we use the path provided in the Field Column Definition
        const objectPath =
          this.columnEditor?.complexObjectPath ?? fieldName ?? '';
        this.setDeepValue(item, objectPath, newValue);
      } else if (fieldName) {
        item[fieldName] = newValue;
      }
    }
  }

  setDeepValue<T = any>(obj: T, path: string | string[], value: any) { // Customized the set value method to handle the array data
    if (typeof path === 'string') {
      path = path.split('.');
    }

    if (path.length > 1) {
      const e = path.shift();
      if (obj && e !== undefined) {
        let innerObject;
        if (!Array.isArray(obj[e]) && typeof obj[e] != 'object') {
          obj[e] = {};
        }
        this.setDeepValue(obj[e], path, value);
      }
    } else if (obj && path[0]) {
      (obj as any)[(path as any)[0]] = value;
    }
  }
}

我希望这对你有帮助。
向库作者提供种类信息，如有可能，在最新版本中更新setDeepValue方法。
