SpreadJS add the function SJS.TABLE to get the What-If Analysis Data Table results.
The SJS.TABLE function simulates inputting the value from inputs into input_cell , and then retrieves the value from result reference as the SJS.TABLE function result.
Argument
Description
result_reference
The cell location to retrieve the value. When all inputs are rows, it can be a range of 1 row and multiple columns. vice versa.
inputs
The values to input into input_cell. It can be a reference, an array, or a value.
input_cell
The cell to input the value. Must be a cell reference.
SJS.TABLE can completely cover traditional Data Table
Scenario
Traditional Data Table
Use SJS.TABLE
one-variable data table
Create DataTable A2:C10with column cell reference A2
B3: =SJS.TABLE(B2:C2,A3:A10,A2)
one-variable data table
Create DataTable A2:H5with row cell reference A2
B3: =SJS.TABLE(A3:A5,B2:H2,A2)
two-variable data table
Create DataTable A2:H5 with column cellreference A1 and row cell reference B1
B3: =SJS.TABLE(A2,B2:H2,B1,A3:A5,A1)
The What-If Analysis Data Table from Excel file will be transformed to SJS.TABLE function formula when importing.
When exporting to Excel, it attempts to convert to an Excel data table; if this fails, the formulas will be preserved.
SJS.TABLE is flexible
SJS.TABLE can use the various input
SJS.TABLE can use as the function parameter
