CSS How to select input_html/css_WEB-ITnose of specified columns

The table has 20 rows, each row has 10 columns, and there is input in each column. I want to set styles for the inputs in different columns. Setting them one by one is too troublesome, and the code is bloated.

How to directly select, enter which column and set the style. For example:

Specify: columns 1, 2, 3, 5, and 9 are one style, and columns 4, 6, 7, 8, and 10 are another style.

table tr td: nth-child(5) input{background:#0f0;}

Thank you slwsss, let me ask again, I used #table1 tr td{ height:20} to set a height for the TD of the table.

How to reset the height of the first row of the table? Setting it with thead td seems to be useless, it is always 20.
