Max columns in html table

what 开发者_开发知识库is the max. no of columns and rows in a html table? Are there any browser issues while viewing the table?

No. There is no as such limit to rows & columns. But

1. It will definitely add horizontal & vertical scroll to your page. Too much scrolling can make your page practically impossible to view.
2. Also your page size will increase a lot causing performance issue.
3. Use will loose interest in your page, due to too much contents & bad user experience

Trawling the DOM with Javascript would adversely effect page performance, case depending.

If it's worth asking then it's worth testing it out, pick a big number and see if you crash your browser:

var t = document.getElementById('t')
var n = document.getElementById('n')
function cols(){
  t.innerHTML = '<tr>'+'<td>x</td>'.repeat(n.value)+'</tr>'
}
function rows(){
  t.innerHTML = '<tr><td>x</td></tr>'.repeat(n.value)
}

<input id="n" placeholder="How many? / Wie viele?"/>
<button type="button" onclick="rows()">Make rows</button>
<button type="button" onclick="cols()">Make cols</button>
<table id="t">
</table>

Don't pick a big number unless you don't have any important stuff open.
