Table border color in JSON

Hi JoaoMarcelino ,

I am also facing similar issue. I followed the suggestion you made but not sure why it is not working in my case. Still I am unable to invoke left and right border to the grid. If possible can you please correct my mistake.

{
	"name": "TableTemplate",
	"visualStyles": {
		"tableEx": {
			"*": {
				"grid": [{
					"gridVertical": true,
					"gridVerticalColor": { "solid": { "color": "#D3D3D3"}},
					"gridVerticalWeight": 1,
					"gridHorizontal": true,
					"gridHorizontalColor": { "solid": { "color": "#D3D3D3"}},
					"gridHorizontalWeight": 1,
					"gridBorder": true,
					"gridBorderColor": { "solid": { "color": "#D3D3D3"}},
					"gridBorderWeight": 1,
					"rowPadding": 5,
					"outlineColor": { "solid": { "color": "#D3D3D3"}},
					"outlineWeight": 1,
					"textSize": 8,
					"imageHeight": 100
				}],
				"columnHeaders": [{
					"fontColor": { "solid": { "color": "#FFFFFF"}},
					"backColor": { "solid": { "color": "#808080"}},
					"outline": "Frame",

					"fontFamily": "Segoe UI",
					"fontSize": 8,
					"alignment": "Center",
					"wordWrap": true,
					"bold": true
					
				}],

					"fontColorPrimary": { "solid": { "color": "#252423"}},
					"backColorPrimary": { "solid": { "color": "#FFFFFF"}},
					"fontColorSecondary": { "solid": { "color": "#252423"}},
					"backColorSecondary": { "solid": { "color": "#FFFFFF"}},
					"outline": "Frame",
					"urlIcon": true,
					"wordWrap": true,
					"fontFamily": "Segoe UI",
					"fontSize": 8
				}],
				"total": [{
					"totals": true,
					"fontColor": { "solid": { "color": "#FFFFFF"}},
					"backColor": { "solid": { "color": "#808080"}},
					"outline": "Frame",
					"fontFamily": "Segoe UI",
					"fontSize": 8,
					"bold": true
				}],
				"stylePreset": [{ 
					"name": "BoldHeader"
				}],
				"border":[{
					"show" :true ,
					"color": { "solid": { "color": "#808080"}},
					"radius": 0
				}],
				"title": [{
					"show": true,
					"text":  "Enter Title Using Title Property",
					"alignment": "center",
					"fontColor": { "solid": { "color": "#FFFFFF" } },
					"background": { "solid": { "color": "#808080" } },
					"fontSize": 13,
					"fontFamily": "Calibri",
					"bold": true
				}]
			}
		}
	}
}

Thanks in advance.
