I have identified a discrepancy in behavior of Telerik Spreadsheet vs Excel in treatment of array formulae (multiplication of arrays)
The spreadsheet attached contains two examples on how the difference on how Excel and Kendo spreadsheets handle array formulas is impacting the tool I'm developing.
The first example is a simple multiplication between a one-column range and a two-column range. Since both have the same number of Rows, Excel multiples both columns of Array 2 by the Array 1 and sum them
Kendo instead expects both ranges to have the same dimensions, so the same array formula throws an error when opened on Kendo
The second example is a the sum of a multiplication between two same-sized matrixes, but conditioned to a flag array. If the flag for that row is true, then the multiplication of the elements of that row should be added to the final result. On Excel, it works as expected.
On the other hand, Kendo seems to consider the “Flag” matrix as a 2-column matrix with the second column left blank, so the result is the multiplication of the first column of array 1 by the first column of array two, conditioned by the flag array:
You can check the results uploading the attached spreadsheet to the Demo available online: https://demos.telerik.com/kendo-ui/spreadsheet/index
Please let me know your feedback and when/if we can expect an alignment of Spreadsheet behavior to Excel's
