ExcelJS - How to handle “computed columns” with addRowsAsync












1














I'm using the ExcelJs API with addRowsAsync() and deleteAllDataValuesAsync(). (reference)



If the user creates some "computed columns" in the Excel sheet, which enlarge the size of the table (e.g.: a new column with the value of the first column + 1), when I want add new data to the table, how should I handle the "computed" column/s?



let excelTable = currentWorksheet.tables.getItemOrNullObject(tableName)
excelTable.rows.load("values")
excelTable.columns.load("values")

return context.sync().then(() => {
if (excelTable.isNullObject) {
excelTable = currentWorksheet.tables.add(tableRange, true)
excelTable.name = tableName
excelTable.getHeaderRowRange().values = [excelHeaders]

return context.sync().then(() => {
Office.context.document.bindings.addFromNamedItemAsync(
tableName,
Office.BindingType.Table,
{ id: tableName },
function(result) {
if (result.status === Office.AsyncResultStatus.Succeeded) {
Office.context.document.bindings.getByIdAsync(
tableName,
null,
(asyncResult: any) => {
var binding = asyncResult.value
binding.addRowsAsync(_excelData)
}
)
} else {
Debug.error("Error:", result.error.message)
}
}
)
})
} else {
const tableRows = excelTable.rows.items.length
const tableColumns = excelTable.columns.items.length
const dataRows = _excelData.length
const dataColumns = _excelData[0].length

Office.context.document.bindings.getByIdAsync(
tableName,
null,
(asyncResult: any) => {
var binding = asyncResult.value
binding.deleteAllDataValuesAsync()
binding.addRowsAsync(_excelData)
}
)
}

excelTable.getRange().format.autofitColumns()
excelTable.getRange().format.autofitRows()

return context.sync()
})


Using Excel for Windows, the new rows aren't added to the table.



Differenly happens if I use Excel Online: the rows are added and the computed column is correctly left "untouched".



Is it a bug of the API?
Can you help me?



Thanks in advance,
Andrea
