Minimum width of first table column

I was surprised to find out that min-width doesn't do the trick. However, after playing with it for a while, I came across this solution:

td:first-child {
    width: 40%;
    white-space: nowrap;
}

I would suggest you to try this to fix the table width in css

    table-layout:fixed;

and in JavaScript syntax is: object.style.tableLayout="fixed"
