📊 jQuery Grid (pqGrid) – Column Selection Features

pqGrid supports Excel-like column selection that allows users to interact with entire columns of data.
Columns can be selected via mouse, keyboard shortcuts, or API methods.

🔹 User Interaction (Mouse & Keyboard)

• Single Column Selection
  • Click on a column header to select the entire column.
• Multiple Non-Contiguous Columns
  • Hold Ctrl (Windows) or Cmd (Mac) and click on multiple column headers.
• Contiguous Column Selection
  • Hold Shift and click between two column headers to select all columns in between.
• Copy & Cut
  • Ctrl + C → Copy selected columns.
  • Ctrl + X → Cut selected columns.

🔹 Programmatic Column Selection (API)

pqGrid provides API methods to select and manipulate columns programmatically:

• select({ colIndx }) → Select a specific column by index.
• range({ c1, c2 }) → Select a contiguous range of columns.
• getSelection() → Retrieve currently selected columns.
• removeSelection() → Clear column selection.

🔹 Range Object for Columns

The Range API can be applied to columns:

• Properties:
  • c1 → Starting column index
  • c2 → Ending column index
  • cc → Column count
• Example:

  // Selects columns from index 1 to 3
  grid.Range({ c1: 1, c2: 3 }).select();
