[Table] EditableCell doesn't grow to match the row like EditableName does with defaultRowHeight set

[seansfkelley]

Bug report

• Package version(s): core: 1.20.0, table: 1.17.0
• Browser and OS versions: Chrome 58.0.3029.110, OS X 10.12.5

Steps to reproduce

<Table numRows={1} defaultRowHeight={30}>
    <Column
        name="foo"
        renderCell={() => <EditableCell/>}
        renderColumnHeader={() => <ColumnHeaderCell renderName={() => <EditableName/>} />}
    />
</Table>

Actual behavior

Header has the right size:

But the cell doesn't:

Expected behavior

EditableCells grow to fit the size of their containing row.

This is extra sad because then the click target for the editable area is small even if the row is very large.

To be clear, if we do this, it's going to look something like this:

Is that really what we want? @llorca

[gscshoyru]

To be clear -- none of the text goes onto other lines, there, it's all on one line, even with all the vertical space.

[llorca]

@gscshoyru yeah that makes sense to me. One liner as a default, but theoretically text could wrap onto multiple lines if wrapping enabled

[gscshoyru]

@llorca -- well, right now we just have inputs -- we'd need textarea to be able to do wrapping -- something to look into later -- but yeah, just wanted to be sure.
