TeeGrid Fast，Light，Snappy Grid Component。
Huge data - capable of handling a very big number of cells. For example 1 billion cells (1000 columns by 1 million rows).
Virtual data - TVirtualData or derived class to automatically create columns and provide cell values.
TStringGrid emulation - TeeGrid can be used like a TStringGrid with a TStringsData object.
Sub-columns (any column can have children columns)
Per-column formatting (font, back fill, stroke, text alignment)
Individual row heights (per-row custom height)
Row groups - Any row can be expanded to show its detail sub-grid rows. The grid Data class must support master-detail relationships.
Totals and SubTotals - Automatic summary "grid bands" can be added to a header or footer, also for "detail" subgrids.
Row "Sub-Bands" - Any row might display a grid band above the row. The "band" can be anything, from a simple TTitleBand to a complex group of bands or rows.
Custom cell rendering - Default class for cell rendering is TCellRender. Other classes can be used or created to override the default behaviour, like for example to show check-boxes in columns with boolean (True/False) values.
Cell text format (float, date-time formatting strings).
Column Visible and Expanded (for sub-columns).
Automatic column width (or fixed, in pixels or % percent of grid width).
Column mouse drag resizing.
Automatic scroll bars visibility - Scrollbars are automatically displayed when necessary. In Firemonkey they can be customized.
Column ordering - Columns and sub-columns can be re-positioned.
Grid Header formatting (font, back fill, stroke).
Grid Header mouse-hover.
Grid "indicator" column (left-most column with symbol for current row).
Row highlighting (mouse-hover and selected row formatting).
Multi-cell range selection (by mouse and arrow keys).
Copy selected cells to clipboard in CSV format, pressing Ctrl+C or Ctrl+Insert key and also by code.
Full selected row highlight.
Grid and Columns ReadOnly.
Custom Grid editors.
Rows and Columns lines separators (stroke settings).
Cell mouse-hover (highlights cell under mouse cursor).
All coordinates as floats - For sub-pixel finetuning, Firemonkey only. VCL always rounds to integer pixels.
Alternate row background filling (back brush, stroke settings).
