Please use CellTextStyle for setting font color.

好的。谢谢

我想实现的，比如分数100 标记绿色，不及格标记红色

bgColor := charts.Color{
    R: 16,
    G: 22,
    B: 30,
    A: 255,
}
p, err = charts.TableOptionRender(charts.TableChartOption{
    Header: []string{
        "Name",
        "Price",
        "Change",
    },
    BackgroundColor:       bgColor,
    HeaderBackgroundColor: bgColor,
    RowBackgroundColors: []charts.Color{
        bgColor,
    },
    HeaderFontColor: drawing.ColorWhite,
    FontColor:       drawing.ColorWhite,
    Padding: charts.Box{
        Top:    15,
        Right:  10,
        Bottom: 15,
        Left:   10,
    },
    Data: [][]string{
        {
            "Datadog Inc",
            "97.32",
            "-7.49%",
        },
        {
            "Hashicorp Inc",
            "28.66",
            "-9.25%",
        },
        {
            "Gitlab Inc",
            "51.63",
            "+4.32%",
        },
    },
    TextAligns: []string{
        "",
        charts.AlignRight,
        charts.AlignRight,
    },
    CellTextStyle: func(tc charts.TableCell) *charts.Style {
        style := charts.Style{
        }
        style.FillColor = drawing.ColorBlue
        style.FontColor = drawing.ColorRed

        return &style
    },

按你说的设置了还是没生效。我还没加数据判断

可根据Column与Row来指定颜色，或者根据Text转换回数值再判断也可以。若还有问题，提供完整的可执行的代码示例。

package main

import (
    "fmt"
    "os"

    "github.com/vicanso/go-charts/v2"
    "github.com/wcharczuk/go-chart/v2/drawing"
)

func main() {
    header := []string{
        "Name",
        "Age",
        "Address",
        "Tag",
        "Action",
    }
    data := [][]string{
        {
            "John Brown",
            "32",
            "New York No. 1 Lake Park",
            "nice, developer",
            "Send Mail",
        },
        {
            "Jim Green  ",
            "42",
            "London No. 1 Lake Park",
            "wow",
            "Send Mail",
        },
        {
            "Joe Black  ",
            "32",
            "Sidney No. 1 Lake Park",
            "cool, teacher",
            "Send Mail",
        },
    }

    p, err := charts.TableOptionRender(charts.TableChartOption{
        Header: header,
        Data:   data,
        CellTextStyle: func(tc charts.TableCell) *charts.Style {
            if tc.Row == 0 && tc.Column == 0 {
                return &charts.Style{
                    FontColor: drawing.ColorBlue,
                }
            }
            fmt.Println(tc.Row)
            fmt.Println(tc.Column)
            return nil
        },
    })
    if err != nil {
        panic(err)
    }

    buf, err := p.Bytes()
    if err != nil {
        panic(err)
    }
    os.WriteFile("./test.png", buf, 0600)
}

hello，新年好，（整行字指定文字颜色，指定背景颜色都搞定了，现在又遇到新的问题） 1708508331386

如图所示： 1.想在特定列加一行用来区分内容项目｜内容比如红色

2.想给某个单元格增加 border 如同蓝色部分，这2个如何实现呀，求教

`package main

import ( "fmt" "os"

"github.com/vicanso/go-charts/v2"
"github.com/wcharczuk/go-chart/v2/drawing"

)

func main() { header := []string{ "Name", "Age", "Address", "Tag", "Action", } data := [][]string{ { "John Brown", "32", "New York No. 1 Lake Park", "nice, developer", "Send Mail", }, { "Jim Green ", "42", "London No. 1 Lake Park", "wow", "Send Mail", }, { "Joe Black ", "32", "Sidney No. 1 Lake Park", "cool, teacher", "Send Mail", }, }

p, err := charts.TableOptionRender(charts.TableChartOption{
    Header: header,
    Data:   data,
    CellTextStyle: func(tc charts.TableCell) *charts.Style {
        if tc.Row == 0 && tc.Column == 0 {
            return &charts.Style{
                FontColor: drawing.ColorBlue,
            }
        }
        fmt.Println(tc.Row)
        fmt.Println(tc.Column)
        return nil
    },
})
if err != nil {
    panic(err)
}

buf, err := p.Bytes()
if err != nil {
    panic(err)
}
os.WriteFile("./test.png", buf, 0600)

}`
