Scrapy Csv export has all extracted data in one cell - scrapy

Question

I am currently building my first scrapy project. Currently I am trying to extract data from a HTML table. Here is my crawl spider so far:
import scrapy
from scrapy.spiders import CrawlSpider, Rule
from scrapy.linkextractors import LinkExtractor
from digikey.items import DigikeyItem
from scrapy.selector import Selector
class DigikeySpider(CrawlSpider):
name = 'digikey'
allowed_domains = ['digikey.com']
start_urls = ['https://www.digikey.com/products/en/capacitors/aluminum-electrolytic-capacitors/58/page/3?stock=1']
['www.digikey.com/products/en/capacitors/aluminum-electrolytic-capacitors/58/page/4?stock=1']
rules = (
# Extract links matching 'category.php' (but not matching 'subsection.php')
# and follow links from them (since no callback means follow=True by default).
Rule(LinkExtractor(allow=('/products/en/capacitors/aluminum-electrolytic-capacitors/58/page/3?stock=1', ), deny=('subsection\.php', ))),
)
def parse_item(self, response):
item = DigikeyItem()
item['partnumber'] = response.xpath('//td[#class="tr-mfgPartNumber"]/a/span[#itemprop="name"]/text()').extract()
item['manufacturer'] = response.xpath('///td[6]/span/a/span/text()').extract()
item['description'] = response.xpath('//td[#class="tr-description"]/text()').extract()
item['quanity'] = response.xpath('//td[#class="tr-qtyAvailable ptable-param"]//text()').extract()
item['price'] = response.xpath('//td[#class="tr-unitPrice ptable-param"]/text()').extract()
item['minimumquanity'] = response.xpath('//td[#class="tr-minQty ptable-param"]/text()').extract()
yield item
parse_start_url = parse_item
It scrapes the table at www.digikey.com/products/en/capacitors/aluminum-electrolytic-capacitors/58/page/4?stock=1. It then exports all data to a digikey.csv file but all data is in one cell.
Csv file with scraped data in one cell
setting.py
BOT_NAME = 'digikey'
SPIDER_MODULES = ['digikey.spiders']
NEWSPIDER_MODULE = 'digikey.spiders'
# Crawl responsibly by identifying yourself (and your website) on the user-agent
USER_AGENT = 'digikey ("Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.93 Safari/537.36")'
# Obey robots.txt rules
ROBOTSTXT_OBEY = False
I want the information scraped with one line at a time with the corresponding information associated with that partnumber.
items.py
import scrapy
class DigikeyItem(scrapy.Item):
partnumber = scrapy.Field()
manufacturer = scrapy.Field()
description = scrapy.Field()
quanity= scrapy.Field()
minimumquanity = scrapy.Field()
price = scrapy.Field()
pass
Any help is much appreciated!

The problem is that you're loading into each field of a single item the whole columns. I feel that what you want is something like:
for row in response.css('table#productTable tbody tr'):
item = DigikeyItem()
item['partnumber'] = (row.css('.tr-mfgPartNumber [itemprop="name"]::text').extract_first() or '').strip()
item['manufacturer'] = (row.css('[itemprop="manufacture"] [itemprop="name"]::text').extract_first() or '').strip()
item['description'] = (row.css('.tr-description::text').extract_first() or '').strip()
item['quanity'] = (row.css('.tr-qtyAvailable::text').extract_first() or '').strip()
item['price'] = (row.css('.tr-unitPrice::text').extract_first() or '').strip()
item['minimumquanity'] = (row.css('.tr-minQty::text').extract_first() or '').strip()
yield item
I've changed a bit the selectors to try to make it shorter. btw please avoid the manual extract_first and strip repetitions that I've used here (just for testing purposes), and consider using Item Loaders, it should be easier to take the first and strip/format the desired output.
