This article mainly introduces "how to use element table components". In daily operation, I believe many people have doubts about how to use element table components. The editor consulted all kinds of data and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the doubts about how to use element table components. Next, please follow the editor to study!

Let column = [

{label: "user id", prop: "userId"}

{label: "user name", prop: "userName"}

{label: "creation date", prop: "createData"}

]

Let data = [

{

UserId:1

UserName: Zhang San

CreateData:'2020-05-26 12 1015 56'

}

{

UserId:2

UserName: "Li Dog Egg"

CreateData:'2020-05-26 12 1015 56'

}

]

Let resolveColumn = _ cmptWidth (column,data)

Console.log (resolveColumn)

/ / [

/ / {label: "user id", prop: "userId", width: ""}

/ / {label: "user name", prop: "userName"}

/ / {label: "creation date", prop: "createData"}

/ /]

_ cmptWidth (min=30,column,data) {

/ / Field length container

Let temp= {}

/ / initialize the field length container based on the first row of data

Object.keys (data [0]) .forEach (key= > {

Temp [key] = []

})

/ / the field length of each row of data is stored in the field length container as 2 characters in Chinese and 1 in English.

Data.map (I = > {

Object.keys (I) .forEach (key= > {

Let str = I [key] & & I [key] .toString ()

Let cn = str & & str.match (/ [\\ u4e00 -\\ u9fa5] / g) & & str.match (/ [\\ u4e00 -\\ u9fa5] / g) .length | | 0

Let en = str & & str.match (/ [A-Za-z0-9] / g) & & str.match (/ [A-Za-z0-9] / g) .length | 0

Let len = Math.max (en + cn*2 +, 10)

Temp [key] .push (Math.min (len,min))

})

})

/ / return the column that adds the column width attribute

Return column.map (I = > {

Let width = Math.ceil (temp [i.prop] .reduce ((aforme b) = > aquib) / rows.length)

Return {

... i

Width:width*12+'px'

}

})
