Class TableCellUpdateEvent

A new value for one cell – the input of TableApi.updateCells. The value is written into the area model; if the cell is visible, only this cell is redrawn. cssClasses are applied to the current drawing of the cell (e.g. a short "flash"); permanent colours belong into the model (AreaModelIf.getCustomClassesAt).

Example

tableApi.updateCells([
  new TableCellUpdateEvent("body", row, 2, price, { "tick-up": up, "tick-down": !up }),
  new TableCellUpdateEvent("body", row, 4, volume)
]);
