ColumnsByAlphaNumericName / Select Layer

Select columns based on alphanumeric name matching. Similar to pandas' filter() or dplyr's select() with regex patterns. This operation identifies and selects columns containing alphanumeric patterns while preserving their original order.

Common applications:

• Selecting numbered feature columns (feature1, feature2, etc.)
• Filtering versioned columns (data_v1, data_v2)
• Extracting sequential measurements (reading_1, reading_2)
• Processing time-series columns (t0, t1, t2)
• Handling multi-batch data (batch_001, batch_002)

Particularly useful in:

• Scientific data analysis
• Longitudinal studies
• Sensor data processing
• Version control systems
• Automated data pipelines
