Generating big tables with time cells results with corrupted file #643
Description
Description
Generating big table with time columns output file is corrupted.
Steps to reproduce the issue:
here is example script
`package main
import (
"flag"
"fmt"
"github.com/360EntSecGroup-Skylar/excelize"
"math/rand"
"reflect"
"strconv"
"time"
)
type NullTime struct {
Time time.Time
Valid bool // Valid is true if Time is not NULL
}
func main() {
r := rand.New(rand.NewSource(99))
excel := excelize.NewFile()
sheetName := "Test sheet"
sheetIndex := excel.GetActiveSheetIndex()
excel.SetSheetName(excel.GetSheetName(sheetIndex), sheetName)
dateStyle, _ := excel.NewStyle(`{"custom_number_format": "yyyy-mm-dd"}`)
floatStyle, _ := excel.NewStyle(`{"number_format": 2}`)
rowsCount := flag.Int("rows", 100, "Number of rows")
flag.Parse()
for row := 1; row <= *rowsCount; row++ {
for col := 1; col <= 10; col++ {
val := randate()
t := reflect.ValueOf(val)
_ = excel.SetCellValue(sheetName, intToCharIndex(col)+strconv.Itoa(row), t.Interface())
_ = excel.SetCellStyle(sheetName, intToCharIndex(col)+strconv.Itoa(row), intToCharIndex(col)+strconv.Itoa(row), dateStyle)
}
for col := 11; col <= 101; col++ {
_ = excel.SetCellValue(sheetName, intToCharIndex(col)+strconv.Itoa(row), r.Float64())
_ = excel.SetCellStyle(sheetName, intToCharIndex(col)+strconv.Itoa(row), intToCharIndex(col)+strconv.Itoa(row), floatStyle)
}
}
if err := excel.SaveAs("Test.xlsx"); err != nil {
fmt.Println(err)
}
}
func intToCharIndex(i int) string {
col, _ := excelize.ColumnNumberToName(i+1)
return col
}
func randate() time.Time {
min := time.Date(2010, 1, 0, 0, 0, 0, 0, time.UTC).Unix()
max := time.Date(2020, 1, 0, 0, 0, 0, 0, time.UTC).Unix()
delta := max - min
sec := rand.Int63n(delta) + min
return time.Unix(sec, 0).UTC()
}
`
making some 100 or 1000 rows output file is ok, making 10k rows file is corrupted.
