.. _auto_definetable_get_curve_by_value:

*RETURN THE CURVES THAT MATCHES THE VALUE OF THE DEFINE TABLE*
==============================================================

Looks up and returns the curve associated with a specific value from a define-table (value-curve pair mapping). Use this worker when you need to retrieve the matching curve for a given scalar key from a structured define table.

Inputs
------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20 20 20

     - Default
     - Required
     - Description
   * - Define Table
     - dt1
     - define_table
     - —
     - 
     - A define-table containing value-to-curve pair mappings; each row associates a scalar key with a curve object — provide the table from which the lookup will be performed.
   * - Value
     - value
     - scalar
     - —
     - 
     - The scalar key value used to look up the matching curve in the define table; must match one of the keys defined in dt1.
