[BUG] Can't create columns in typescript

🐛 Bug Report

I have created worksheet and using that worksheet i cant seems to create columns header.

const workbook = new Workbook();
workbook.creator = workbookName;

const worksheet = workbook.addWorksheet(workSheetName);
worksheet.columns = [
    { header: 'Id', key: 'id', width: 10 },
    { header: 'Name', key: 'name', width: 32 },
    { header: 'D.O.B.', key: 'DOB', width: 10, outlineLevel: 1 },
];

Error give. Type '{ header: string; key: string; width: number; }' is missing the following properties from type 'Column': outlineLevel, hidden, style, values, and 11 more.

It just seems like under Type Columns all is required.

Lib version: 4.2.0

Steps To Reproduce

const workbook = new Workbook();
workbook.creator = workbookName;

const worksheet = workbook.addWorksheet(workSheetName);
worksheet.columns = [
    { header: 'Id', key: 'id', width: 10 },
    { header: 'Name', key: 'name', width: 32 },
    { header: 'D.O.B.', key: 'DOB', width: 10, outlineLevel: 1 },
];

The expected behaviour:

Type '{ header: string; key: string; width: number; }' is missing the following properties from type 'Column': outlineLevel, hidden, style, values, and 11 more.

Possible solution (optional, but very helpful):

Make fields in Type Columns optional

Where is the ExcelProper coming from @KingDarBoja ? I don’t see it in this lib.

@Artaud ExcelProper is just your default import of the library. You can name it differently.

import ExcelJS from 'exceljs';

worksheet.columns = [
    {header: 'id', key: 'id', width: 10},
] as ExcelJS.Column[];

You can cast if you are using 4.2 in the meantime:

const workbook = new Workbook();
workbook.creator = workbookName;

const worksheet = workbook.addWorksheet(workSheetName);
worksheet.columns = [
    { header: 'Id', key: 'id', width: 10 },
    { header: 'Name', key: 'name', width: 32 },
    { header: 'D.O.B.', key: 'DOB', width: 10, outlineLevel: 1 },
] as as ExcelProper.Column[]; // :)
