Table cell copy in IE 11

[chuyachia]

Environment

• Package version(s): blueprintjs/table v.3.7.0
• Browser and OS versions: IE 11 Win7

If possible, link to a minimal repro (fork this code sandbox): https://blueprintjs.com/docs/#table/features.sorting

Steps to reproduce

Follow the table documentation page instruction to select cell and copy in IE11

Actual behavior

No data was copied. Got an Unexpected call to method or property access. error.

Expected behavior

IE 11 is among the browsers that Blueprint supports. The data should be copied.

Possible solution

It seems that DataTransfer.setData only accepts "text" format in IE11 but "text/html" and "text/plain" are used in https://github.com/palantir/blueprint/blob/develop/packages/table/src/common/clipboard.ts#L107 One solution might be just using "text" as format?

[chuyachia]

@adidahiya Do you think using just "text" instead of "text/html" and "text/plain" can be a solution?

@chuyachia you're welcome to test it out -- just make sure the behavior for other browsers continues to work.
