Вы можете установить фоновые ячейки динамически, используя Условное форматирование драгоценного камня write_xlsx .
Вот пример из файла gemfile:
#!/usr/bin/env ruby
# -*- coding: utf-8 -*-
require 'rubygems'
require 'write_xlsx'
workbook = WriteXLSX.new('conditional_format.xlsx')
worksheet1 = workbook.add_worksheet
# Light red fill with dark red text.
format1 = workbook.add_format(
:bg_color => '#FFC7CE',
:color => '#9C0006'
)
# Green fill with dark green text.
format2 = workbook.add_format(
:bg_color => '#C6EFCE',
:color => '#006100'
)
# Some sample data to run the conditional formatting against.
data = [
[ 90, 80, 50, 10, 20, 90, 40, 90, 30, 40 ],
[ 20, 10, 90, 100, 30, 60, 70, 60, 50, 90 ],
[ 10, 50, 60, 50, 20, 50, 80, 30, 40, 60 ],
[ 10, 90, 20, 40, 10, 40, 50, 70, 90, 50 ],
[ 70, 100, 10, 90, 10, 10, 20, 100, 100, 40 ],
[ 20, 60, 10, 100, 30, 10, 20, 60, 100, 10 ],
[ 10, 60, 10, 80, 100, 80, 30, 30, 70, 40 ],
[ 30, 90, 60, 10, 10, 100, 40, 40, 30, 40 ],
[ 80, 90, 10, 20, 20, 50, 80, 20, 60, 90 ],
[ 60, 80, 30, 30, 10, 50, 80, 60, 50, 30 ]
]
# This example below highlights cells that have a value greater than or
# equal to 50 in red and cells below that value in green.
caption = 'Cells with values >= 50 are in light red. ' +
'Values < 50 are in light green'
# Write the data.
worksheet1.write('A1', caption)
worksheet1.write_col('B3', data)
# Write a conditional format over a range.
worksheet1.conditional_formatting('B3:K12',
{
:type => 'cell',
:format => format1,
:criteria => '>=',
:value => 50
}
)
# Write another conditional format over the same range.
worksheet1.conditional_formatting('B3:K12',
{
:type => 'cell',
:format => format2,
:criteria => '<',
:value => 50
}
)
workbook.close
Выходной файл будет выглядеть так:
