Redundant tag in source code when inserting a new row in a table

When inserting a new row in a table, the source code adds a redundant string of colspan="1". Steps to reproduce the problem: * Create a 2*2 table. * Click the bottom row. Insert a new row below, so that the bale is 3*2 now. * View the source code. A redundant colspan="1" appears in Version 7.5

Hello @[deleted]!

As I understand, you noticed that after adding a new row in a table, the colspan tag is added with the value of 1 to that newly added row.

The colspan default value is indeed 1, as specified by the HTML standard. However, I was unable to find, within the HTML standard, an article that specifies if the tag should be either skipped or explicitly used when the desired value is 1.

I found, however, that tables may contain the colspan tag:

The td and th elements may have a colspan content attribute specified, whose value must be a valid non-negative integer greater than zero and less than or equal to 1000.

As I understand, even by using the colspan tag with the value of 1 it falls within the specification for HTML.

The website I read for the standard definition is this:

* [HTML Living Standard — Last Updated 10 July 2020] .9.11 Attributes common to td and th elements

With this in mind, I would like to understand a few points. Here they are:

* Are you facing some kind of issue with tables?
* Are tables behaving as expected?

Let us hear from you!
