Power BI Theme : Table

Hi,

Regarding Power BI Theme, which you can create as JSON file. has anyone know what is the tag name for Table -Style ?

I know the visual name 'tableEx', but when I added tag "Style", my theme does not make affect. I try to click Revert to default, so it will look into the imported themes, but the style not changing. I want to make it as "Alternating rows" as default.

Example of the snippet code of JSON themes :

"tableEx": {
    "*": {
  "columnHeaders": [{
     "fontColor": { "solid": { "color": "#f2f2f2"}},
     "backColor": { "solid": { "color": "#999999"}}
  }],
  "style": [{
     "style": "Alternating rows"
  }],
  "values": [{
     "fontColorPrimary": { "solid": { "color": "#e5e5ff"}}
  }]
      }

Thanks
