我有一个表格，其中包含具有相同值的单元格。我试图使用colspan将它们合并在一起，但为colspan设置属性没有任何效果。
https://jsfiddle.net/afn4f1q9/4/
$(function() {
$('table.merge tr').each(function() {
var tr = this;
var counter = 1;
var prevValue = false;
var colspanTD = false;
$('td', tr).each(function(index, value) {
var td = $(this);
if (counter == 1) {
colspanTD = $(this);
}
if (prevValue !== false) {
if (td.text() == prevValue) {
if (td.text() != '' && td.text() != 'X' && td.text() != '*') {
counter++;
td.remove();
}
} else {
$(colspanTD).attr('colspan', counter );
counter = 1;
}
}
prevValue = td.text();
});
});
});

我正在尝试使用colspan将它们合并在一起，但为colspan设置属性没有任何效果。
您的问题与代码的某些问题有关。我解决了问题。这是我的提议（参见代码中的注释）。
$('table.merge tr').each(function () {
var tr = this;
var counter = -1;
var prevValue = false;
var colspanTD = false;
//
// save current selection
//
var tableCells = $('td', tr)
tableCells.each(function (index, value) {
var td = $(this);
if (prevValue !== false) {
if (td.text() == prevValue) {
//
// get text, trim it and transform in uppercase
//
var txt = td.text().trim().toUpperCase();
if (txt != '' && txt != 'X' && txt != '*') {
//
// set the starting cell sequence...
//
if (colspanTD === false) {
counter = 1;
colspanTD = tableCells.eq(index - 1);
}
counter++;
td.remove();
}
} else {
//
// if ending cell sequence...
//
if (colspanTD !== false) {
colspanTD.attr('colspan', counter);
colspanTD = false;
}
}
}
prevValue = td.text();
});
//
// if ending cell sequence in row...
//
if (colspanTD !== false) {
colspanTD.attr('colspan', counter);
colspanTD = false;
}

试试这个：
else {
this.colSpan = counter
counter = 1;
}
/**
* And Not,
*
* else {
* $(colspanTD).attr('colspan', counter );
* counter = 1;
* }
*/
顺便说一下，你的代码有点重复。你可以这样做：
$(function() {
$('table.merge tr').each(function() {
var counter = 1;
var $prevTD = null;
$('td', this).each(function(index, value) {
// We only need the text once.
var $this = $(this);
var text = $this.text();
// We skip if :
// 1. It's the first td.
// 2. If the string is empty.
// 3. The string is a "*" or "X".
// 4. The current text matches the last text.
if ($prevTD && text && !/^[*X]$/.test(text) && text == $prevTD.text()) {
$prevTD.remove();
this.colSpan = ++counter;
}
// We reset our counter
else counter = 1;
// We save the current <td>.
$prevTD = $this;
});
});
