Append rows to existing table

See original GitHub issue

Hello, I’m having an issue when appending new rows to existing table

const workbook = new ExcelJS.Workbook()
workbook.xlsx.readFile(filename).then(async function () {
    let worksheet = workbook.getWorksheet(1)
    let table = worksheet.getTable('MyTable')
    table.addRow(['One','Two'])
    table.commit()
    await workbook.xlsx.writeFile(filename)
})

I’m getting this error :

TypeError: Cannot read property 'length' of undefined
    at Table.get height [as height] (C:\Users\SatSuki\Desktop\FootScrap\node_modules\exceljs\lib\doc\table.js:88:32)
    at Table.get filterHeight [as filterHeight] (C:\Users\SatSuki\Desktop\FootScrap\node_modules\exceljs\lib\doc\table.js:93:21)
    at Table.get tableHeight [as tableHeight] (C:\Users\SatSuki\Desktop\FootScrap\node_modules\exceljs\lib\doc\table.js:98:21)

    at Table.addRow (C:\Users\SatSuki\Desktop\FootScrap\node_modules\exceljs\lib\doc\table.js:322:14)
    at C:\Users\SatSuki\Desktop\FootScrap\spread.js:62:27
    at process._tickCallback (internal/process/next_tick.js:68:7)

When appending just after creating the table it works fine.

Hello, Though I have updated ExcelJs in latest version but I still get the same problem about appending rows to existing table. My code is like const Excel = require('exceljs'); const workbook = new Excel.Workbook(); await workbook.xlsx.readFile(filepath + '/template_file.xlsx'); const mysheet = workbook.getWorksheet('MyWorksheet'); mysheet.unprotect(); const mytable = mysheet.getTable('MyTable'); for (var i: number = 0; i< myArray.length; i++) { mytable.addRow([ myArray[i].field1, myArray[i].field2 ]); } mytable.commit();

When I test with console.log(mytable) and I got Table { worksheet: undefined, table: { name: 'MyTable', displayName: 'MyTable', tableRef: 'A1:N2', totalsRow: false, headerRow: false, columns: [ [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object], [Object] ], autoFilterRef: 'A1:N2', style: { theme: 'TableStyleMedium2', showFirstColumn: false, showLastColumn: false, showRowStripes: true, showColumnStripes: false } } }

Thanks in advance for your help
