使用Array.prototype.filter()过滤Account No（数组的第一个元素）

＆＃13;

let arr = [
  ['Account No.',' Acc. Name',' O/R',' Ack. Receipt',' Date',' Description',' Category',' Credit',' Debit',' P. Method',' Chq. Date',' Chq. No.',' Bank Name',' Deposited'],
  ['0001',' Snow',' ',' ',' Thu Apr 12 20:24:41 GMT+08:00 2018',' H.O.A. dues for month of April',' HOA Dues',' ',' 400.0',' ',' ',' ',' ',''],
  ['0002',' Two',' ',' ',' Thu Apr 12 20:24:41 GMT+08:00 2018',' H.O.A. dues for month of April',' HOA Dues',' ',' 400.0',' ',' ',' ',' ','' ],
  ['0003',' Three',' ',' ',' Thu Apr 12 20:24:41 GMT+08:00 2018',' H.O.A. dues for month of April',' HOA Dues',' ',' 400.0',' ',' ',' ',' ','' ],
  ['0004',' Four',' ',' ',' Thu Apr 12 20:24:41 GMT+08:00 2018',' Monthly accrued interest @ 12% per annum (1% per month) on ageing balance more than 3 months.',' Int. Charge',' ',' 4.0',' ',' ',' ',' ','' ],

  ['0005',' Five',' ',' ',' Thu Apr 12 20:24:42 GMT+08:00 2018',' Monthly accrued interest @ 12% per annum (1% per month) on ageing balance more than 3 months.',' Int. Charge',' ',' 8.0',' ',' ',' ',' ',' '],
  ['0005',' Five',' ',' ',' Thu Apr 12 20:24:42 GMT+08:00 2018',' H.O.A. dues for month of April',' HOA Dues',' ',' 400.0',' ',' ',' ',' ','' ],
  ['0006',' Six',' ',' ',' Thu Apr 12 20:24:43 GMT+08:00 2018',' Monthly accrued interest @ 12% per annum (1% per month) on ageing balance more than 3 months.',' Int. Charge',' ',' 12.0',' ',' ',' ',' ','' ],

]

let filtered = arr.filter(e => e[0] == '0004')

console.log(filtered)

假设你的数组是有效的（带有值的引号），你可以这样简单地过滤它：

＆＃13;

const bigArray = [
	["Account No.", "Acc. Name", "O/R, Ack. Receipt", "Date", "Description", "Category", "Credit", "Debit", "P. Method", "Chq. Date", "Chq. No.", "Bank Name", "Deposited"],
	["0001", "Snow", , , "Thu Apr 12 20:24:41 GMT+08:00 2018", "H.O.A. dues for month of April","HOA Dues", , "400.0", , , , , ],
	["0002", "Two", , , "Thu Apr 12 20:24:41 GMT+08:00 2018", "H.O.A. dues for month of April", "HOA Dues", , "400.0", , , , , ],
	["0003", "Three", , , "Thu Apr 12 20:24:41 GMT+08:00 2018", "H.O.A. dues for month of April", "HOA Dues", , "400.0", , , , , ]
]

let filtered = bigArray.filter( subArray => subArray.includes("0002") )

console.log(filtered)
