[DynMatrix]

addCellBackground = function (self, column, row, pos, index, isHeader) {
self.emitter.emit('cell-background-add', self, column, row, index, isHeader);

    self.pdf
        .rect(pos.x, pos.y, column.width, row._renderedContent.height)
        .fill("#FBF1FB").fillColor('#000000');

    self.emitter.emit('cell-background-added', self, column, row, index, isHeader);

You should be able to set header fill color with headerFill property in your column definition and onCellBackgroundAdd/ed events.

.addColumns([{
  id: 'col',
  header: 'My header',
  headerFill: true // needed so we know we need to fill header cells
}])
.onCellBackgroundAdd(t => t.pdf.fill('#eeeeee')) // set fill color
.onCellBackgroundAdded(t => t.pdf.fill('black')) // reset fill color
