Status bar

The status bar is the strip under the grid that shows live aggregates of the selected cell range - count, sum, average, min, max - the way Excel does at the bottom-right when you select a block of numbers.

<SvGrid {data} {columns} {features} enableCellSelection statusBar />

It needs enableCellSelection (the bar aggregates the selected rectangle). Drag a range across numeric cells and the bar updates instantly.

Choosing aggregates

statusBar={true} shows the default set (count, sum, avg, min, max). Pass an object to pick which:

<SvGrid enableCellSelection statusBar={{ aggregates: ['count', 'sum', 'avg'] }} />

Aggregate	Meaning
`count`	Cells in the selection (non-group).
`numericCount`	How many of those hold a finite number.
`sum`	Sum of the numeric cells.
`avg`	Mean of the numeric cells.
`min` / `max`	Smallest / largest numeric value.

Behavior

The numeric aggregates (sum, avg, min, max) only appear when the selection actually contains numbers - selecting text cells shows just the count.
A single-cell selection shows nothing; the bar appears once a range of two or more cells is selected.
Edited values are respected: the aggregates read the displayed value, so an in-progress edit is reflected.
Group rows are skipped.
