Hello.
From the HTML Node > Operation: Convert to HTML Table, the styling attributes are broken.
For example. If you use this node to generate a table without any custom attributes, the default HTML code for the Table Attributes is:
<table style='border-spacing:0; font-family:helvetica,arial,sans-serif' >
If you try to add a style of background-color: red

the HTML ouput will be:
<table style='border-spacing:0; font-family:helvetica,arial,sans-serif' style="background-color: red">
Clearly this is wrong and not valid. Also if you try to add the background-color without the style=" option, the output HTML code will be:

<table style='border-spacing:0; font-family:helvetica,arial,sans-serif' background-color: red>
This is also wrong HTML code.
The HTML node must add the options inside the already defined table style attributes. So the above example code to be working properly should be:
<table style='border-spacing:0; font-family:helvetica,arial,sans-serif; background-color: red'>
Please fix this.
