在使用js-xlsx导出.xlsx文件时,我想将列宽设置为等于该列内容的最大长度
How to set cell width when export .xlsx files with js-xlsx
我在上面尝试过。
let sheet = workBook.Sheets.Sheet1;
let wscols = [];
const colNode = table.tHead.rows[0].childNodes; // getting the column names from the table rendered on the page
const colNumber = colNode.length;
for(let i = 0; i < colNumber; i++){
wscols.push({
wch: colNode[i].innerText.length * 1.28
})
}
sheet['!cols'] = wscols;
我可以通过从屏幕上呈现的表中获取列的名称来设置宽度。但是我遇到的问题是,假设列名的名称为“ Title”,并且其行具有某些值,如“ Australia”,则列名的长度较小,并且整个列宽均未正确设置。

private autofitColumns(json: any[], worksheet: XLSX.WorkSheet, header?: string[]) {
const jsonKeys = header ? header : Object.keys(json[0]);
let objectMaxLength = [];
for (let i = 0; i < json.length; i++) {
let value = json[i];
for (let j = 0; j < jsonKeys.length; j++) {
if (typeof value[jsonKeys[j]] == "number") {
objectMaxLength[j] = 10;
} else {
const l = value[jsonKeys[j]] ? value[jsonKeys[j]].length : 0;
objectMaxLength[j] =
objectMaxLength[j] >= l
? objectMaxLength[j]
: l;
}
}
let key = jsonKeys;
for (let j = 0; j < key.length; j++) {
objectMaxLength[j] =
objectMaxLength[j] >= key[j].length
? objectMaxLength[j]
: key[j].length;
}
}
const wscols = objectMaxLength.map(w => { return { width: w} });
worksheet["!cols"] = wscols;
}
