 * 2. If range left, right, up, down has value, the range should expand to the cell which has value.
 * 3. If the range has no value, the range should not expand.
 * 4. If the merge has span, the every cell value in span should be the anchor of the span range.
 * 5. The span range should be not part in the result range.
 * @param {IRange} startRange The start range.
