PivotTable
TsgcHTMLComponent_PivotTable — render a Bootstrap pivot table that groups rows and columns and aggregates measures with row, column and grand totals, in Delphi, C++ Builder and .NET.
TsgcHTMLComponent_PivotTable — render a Bootstrap pivot table that groups rows and columns and aggregates measures with row, column and grand totals, in Delphi, C++ Builder and .NET.
Declare the grouping fields and measures, feed it raw rows (or bind a dataset), then read the HTML property.
TsgcHTMLComponent_PivotTable
Bootstrap 5 aggregated table + totals
Delphi, C++ Builder, .NET
Add RowFields / ColumnFields to group by, add a Measures entry per aggregated value, list the source columns in DataFields, push rows with AddRow, then read HTML.

Each entry has a FieldName and Caption; RowFields groups rows down the left, ColumnFields groups columns across the top.
Measures.Add returns a TsgcHTMLPivotMeasure with SourceField, Caption, an Aggregation (SUM/COUNT/AVERAGE/MIN/MAX) and an optional Format picture.
DataFields lists the raw source columns positionally; AddRow(aValues) appends one row matching that order.
LoadFromDataSet(aDataSet) reads only the fields referenced by RowFields, ColumnFields and Measures directly from a TDataSet.
ShowRowTotals, ShowColumnTotals and ShowGrandTotal each toggle a summary row/column; TotalText labels them.
Striped, Bordered, Hover and Compact style the Bootstrap table; EmptyCellText fills empty buckets; HTML returns the finished table.
