In IE, it's unable to edit cell value when not in the edit mode

[souppower]

Env: IE11 (Windows 7)

How to reproduce

• First click on a cell, and type something.
• Then, click on another cell. This, in effect, releases the currently selected cell, and chooses a new cell.

The newly selected cell doesn't accept whatever value you type in.
Clicking on the cell one more time, however, enables you to edit the cell.

Quick fix

Not sure if this is the best fix, but it seems to work.

Add this somewhere In onMouseDown in Datasheet.js

document.addEventListener('keydown', this.handleKey)

Add this somewhere In handleKey in Datasheet.js

document.removeEventListener('keydown', this.handleKey)
