applyTableAttributes altering html width and height attributes

Hi,

Although the description of options.applyTableAttributes reads:
"Whether to apply the border, cellpadding and cellspacing attributes to table elements.",

It seems to have an effect on the width and height html values of tables, in that it adds 'px' to the numbers contained.
example:

```







```

outputs:
```







```

This appears to mess with (my) table rendering D:

If it helps, my gulp task is as follows:
```
gulp.task('inline', function(){
var stylesheet = fs.readFileSync('app/css/styles.css', 'utf8');
return gulp.src('app/html/*.html')
.pipe(inlineCss({
applyStyleTags: false,
removeStyleTags: false,
applyTableAttributes: true,
applyWidthAttributes:false,
preserveMediaQueries: true,
extraCss: stylesheet
}))
.pipe(gulp.dest('dist'));
});
```
