這是在表中打印數(shù)據(jù)的代碼，每列包含多個(gè)數(shù)據(jù)。這樣一來(lái)，每一列就很難打印出準(zhǔn)確的數(shù)據(jù)個(gè)數(shù)。這就是為什么如果數(shù)據(jù)的數(shù)量是三并且循環(huán)的限制是 2 那么它不會(huì)打印最后一個(gè)數(shù)據(jù)列并且循環(huán)將在 2 處停止。如何根據(jù)數(shù)據(jù)調(diào)整列？要求的結(jié)果╔═══╤════════════════╤═════════════════════╗║ # │ Projects │ Project Priorities ║╟━━━┼━━━━━━━━━━━━━━━━┼━━━━━━━━━━━━━━━━━━━━━╢║ 1 │ first project │ None ║║ 2 │ second project │ Low ║║ 3 │ │ Medium ║║ 4 │ │ High ║╚═══╧════════════════╧═════════════════════╝代碼package mainimport ( "fmt" "github.com/alexeyco/simpletable")func InfoTable(allData [][]string) { table := simpletable.New() table.Header = &simpletable.Header{ Cells: []*simpletable.Cell{ {Align: simpletable.AlignCenter, Text: "#"}, {Align: simpletable.AlignCenter, Text: "Projects"}, {Align: simpletable.AlignCenter, Text: "Project Priorities"}, }, } var cells [][]*simpletable.Cell for i := 0; i < 2; i++ { cells = append(cells, *&[]*simpletable.Cell{ {Align: simpletable.AlignCenter, Text: fmt.Sprintf("%d", i+1)}, {Align: simpletable.AlignCenter, Text: allData[0][i]}, {Align: simpletable.AlignCenter, Text: allData[1][i]}, }) } table.Body = &simpletable.Body{Cells: cells} table.SetStyle(simpletable.StyleUnicode) table.Println()}func main() { data := [][]string{ {"first project", "second project"}, {"None", "Low", "Medium", "High"}, } InfoTable(data)}

有一系列可能的方法；這是一個(gè)選項(xiàng)，無(wú)需對(duì)行數(shù)/列數(shù)做出假設(shè)（操場(chǎng)）：
func InfoTable(headings []string, allData [][]string) {
if len(headings) != len(allData) {
panic("Must have a heading per column")
}
table := simpletable.New()
// Populate headings (adding one for the row number)
headerCells := make([]*simpletable.Cell, len(headings)+1)
headerCells[0] = &simpletable.Cell{Align: simpletable.AlignCenter, Text: "#"}
for i := range headings {
headerCells[i+1] = &simpletable.Cell{Align: simpletable.AlignCenter, Text: headings[i]}
}
table.Header = &simpletable.Header{
Cells: headerCells,
}
// Work out number of rows needed
noOfCols := len(allData)
noOfRows := 0
for _, col := range allData {
if len(col) > noOfRows {
noOfRows = len(col)
}
}
// Populate cells (adding row number)
cells := make([][]*simpletable.Cell, noOfRows)
for rowNo := range cells {
row := make([]*simpletable.Cell, noOfCols+1) // add column for row number
row[0] = &simpletable.Cell{Align: simpletable.AlignCenter, Text: fmt.Sprintf("%d", rowNo+1)}
for col := 0; col < noOfCols; col++ {
if len(allData[col]) > rowNo {
row[col+1] = &simpletable.Cell{Align: simpletable.AlignCenter, Text: allData[col][rowNo]}
} else {
row[col+1] = &simpletable.Cell{Align: simpletable.AlignCenter, Text: ""} // Blank cell
}
cells[rowNo] = row
}
}
table.Body = &simpletable.Body{Cells: cells}
table.SetStyle(simpletable.StyleUnicode)
table.Println()
}
