Can't setup fontSize of Column Headers for matrices in custom theme

[orlandom]

Hello,

I'm trying to change the font size of the column headers for matrices. I'm using the following code for the matrices:

"matrix": {
            "*": {
                "columnHeaders": [{
                    "fontSize": 14
                 }]
                 }
                   }

I think the problem is the name of the visual since matrix doesn't appear here.

Please help! Thanks

Just in case, this is the full JSON file for the theme:

{
    "name": "Sunflower Twilight",
    "dataColors": ["#F17925","#004753","#CCAA14","#4B4C4E","#D82C20","#A3D0D4","#536F18","#46ABB0"],
    "background":"#FFFFFF",
    "foreground": "#004753",
    "tableAccent": "#F17925",
	"visualStyles":{
        "*":{
            "*":{
                "*":[{
                    "responsive":true,
				    "wordWrap":true
                }],
			    "wordWrap":[{
				    "show":true
                }],
                "labels":[{
                    "show":true,
                    "labelOrientation":"vertical"
                }],
                "categoryAxis":[{
                    "showAxisTitle":true
                }],
                "valueAxis":[{
                    "showAxisTitle":true
                }]
		    }
	    },
	    "scatterChart":{
		    "*":{
			    "fillPoint":[{
				    "show":true
				}]
		    }
	    },
         "matrix": {
            "*": {
                "columnHeaders": [{
                    "fontSize": 14
                 }]
                 }
                   }
    }
 }

@orlandom,

Use visualName "pivotTable" instead.
