對(duì)于我的 CSV 文件，每一行都有相同的列數(shù)，但對(duì)于最后一行，那只有一列，所以當(dāng)我用“foreach”讀取文件數(shù)據(jù)以獲得總行數(shù)時(shí)，我遇到了錯(cuò)誤字段數(shù)，如何在不刪除最后一行的情況下修復(fù)此錯(cuò)誤？此處的代碼和 CSV 文件：openfile, err := os.Open(filepath)    checkError("Error in reading the file\n", err)    fmt.Println("Already open filepath :", filepath)    //read the data of file    filedata, err := csv.NewReader(openfile).ReadAll()    checkError("Error in reading the file\n", err)    leg := len(filedata)    fmt.Println("total no of rows:", leg)    close := make([]string, leg)    date := make([]string, leg)    open := make([]string, leg)    high := make([]string, leg)    low := make([]string, leg)    adjustclose := make([]string, leg)    volume := make([]string, leg)    for e, value := range filedata {        date[e] = value[0]        open[e] = value[1]        high[e] = value[2]        low[e] = value[3]        close[e] = value[4]        adjustclose[e] = value[5]        volume[e] = value[6]    }2020-03-24,21,21,21,21,21,52020-04-06,20.8,20.8,20.8,20.8,20.8,192020-04-07,20.4,20.4,20.4,20.4,20.4,52020-04-09,20.4,20.4,20.4,20.4,20.4,10292
