How can I do in Highchart to have 1px space between the columns and the y axis?

I need to make a column chart using tall charts having 1px space between the columns and the Y axis, how can I add the 1px space that is in my desired chart to the chart I made is the code I made: (Sorry I don’t have enough reputation to add images that why not post).

var data = [ 20, 29, 25, 29, 21, 17, 20, 19, 18]; 
createMeasuresGraph(data, "quintals-sugar-graph");
function createMeasuresGraph(data, container) {
    data[0] = { color: '#55B647', y: data[0] };
    data[data.length -2 ] = { color: '#F15B49', y: data[data.length -2 ] };
    var chart = new Highcharts.Chart({
        chart: {
            marginBottom: 1,
            marginLeft: 0,
            marginRight: 0,
            marginTop: 0,
            renderTo: container,
            type: 'column',
        },
        credits: {
            enabled: false
        },
        legend: {
            enabled: false
        },
        plotOptions: {
            column: {
                pointWidth: 5,
            },
            series: {
                borderWidth: .1,

            }
        },
        series: [{
            data: data,
            color: '#95D2F3',
            shadow: false,
        }],
        title: {
            text: ''
        },
        tooltip: {
            enabled: false
        },
        xAxis: {
            labels: {
                enabled: false
            },
            title: {
                enabled: false
            },
            lineColor: '#CBCBCB',
            tickWidth: 0
        },
        yAxis: {
            endOnTick: false,
            gridLineWidth: 0,
            labels: {
                enabled: false
            },
            startOnTick: false,
            minPadding: 0.5,
            title: {
                text: ""
            }
        }
    });
}

I also see that the space between them is not the same in all columns, maybe I'm using the wrong aproch to get spaces, what would it be better?

Do you need 1px space between each column?

/ :

var colWidth = ($('#quintals-sugar-graph').width() / data.length) + 1;

borderWidth 1px, :

    plotOptions: {
        column: {
            pointWidth: colWidth,
            borderWidth: 1
        },

    },

Fiddle .

1px? , :

plotOptions: {
    column: {
        pointPadding: 0,
        groupPadding: 0
    }
}

You can simply do:

plotOptions: {
  column: {
    pointPadding: 0,
    groupPadding: 0,
    borderWidth: 1
  }
},
