// TODO. There are several ways to implement a cursor; similar concerns may arise
// when implementing selection and cell editor.
// (1) Class on 'div.field.field_clip'. Fewest elements, seems possibly best for
// performance. Problem is: it's impossible to get cursor exactly right with a
// one-sided border. Attaching a cursor as additional element inside the cell
// truncates the cursor to the cell's inside because of 'overflow: hidden'.
// (2) 'div.field' with 'div.field_clip' inside, on which a class is toggled. This
// works well. The only concern is whether this slows down rendering. Would be
// good to measure and compare rendering speed.
// Related: perhaps the fastest rendering would be for a table.
// (3) Separate element attached to the row, absolutely positioned at left
// position and width of the selected cell. This works too. Requires
// maintaining a list of leftOffsets (or measuring the cell's), and feels less
// clean and more complicated than (2).
// IsRowActive and isCellActive are a significant optimization. IsRowActive is called
// for all rows when cursor.rowIndex changes, but the value only changes for two of the
// rows. IsCellActive is only subscribed to columns for the active row. This way, when
// the cursor moves, there are (rows+2*columns) calls rather than rows*columns.
