*DATASET GET DEFINE TABLE*
==========================

Converts a dataset into a define-table structure by mapping designated columns to value, curve, and name roles. Use this worker when you need to transform a tabular dataset into a structured define-table for downstream parametric or curve-based workflow steps.

When to use
-----------

Classification: **process**.

Tagged: ``column_mapping``, ``dataset``, ``define_table``, ``table_transform``.

Inputs
------

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

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Dataset
     - dataset_1
     - dataset
     - —
     - 
     - Input dataset (tabular) to be converted into a define-table; all column selections below reference columns present in this dataset.
   * - Value Column
     - value_column
     - scalar
     - —
     - 
     - Name of the column in dataset_1 whose entries will populate the 'value' field of each define-table row; leave unset if no scalar value mapping is required.
   * - Curve Column
     - curve_column
     - scalar
     - —
     - 
     - Name of the column in dataset_1 whose entries will populate the 'curve' field of each define-table row; leave unset if no curve association is needed.
   * - Name Column
     - name_column
     - scalar
     - —
     - 
     - Name of the column in dataset_1 whose entries will populate the 'name' field (row label) of each define-table row; leave unset to use default row identifiers.

Outputs
-------

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

   * - Label
     - ID
     - Type
     - Description
   * - dataset_get_define_table_output_1
     - dataset_get_define_table_output_1
     - define_table
     - A define-table object constructed from the input dataset, with rows keyed by the name column and value/curve fields populated from the respective selected columns.
