Style not working properly in addConditionalFormattingRule

[Greenns]

Hi,

BackgroundColor not working with addConditionalFormattingRule() but other style options work fine.

See gist : https://gist.github.com/Greenns/2c323fb366f84f577a60bb115871c063

For the same style:
first cell with addConditionalFormattingRule() and the second with cell().style():

Excel xml file does not have the bgcolor, only the font color is present

<Condition>
    <Value1>test!RC[16379]&lt;test!RC[16380]</Value1>
    <Format Style='font-size:12.0pt;color:#F00000;font-family:Calibri'/>
</Condition>

Fix has now been pushed to NPM with version 1.3.1

I did also need to make an update to the README. It looks like bgColor is required for conditional format fills. in your gist, you'll need to add that as the same color as your fgColor

var myStyle = wb.createStyle({
  font: {
    color:'#F00000',
  },
  fill: {
    type:'pattern',
    patternType:'solid',
    fgColor:'#FFFF00',
  },
});

becomes

var myStyle = wb.createStyle({
  font: {
    color:'#F00000',
  },
  fill: {
    type:'pattern',
    patternType:'solid',
    bgColor:'#FFFF00', // just add this
    fgColor:'#FFFF00',
  },
});
