html - Make columns of equal width in <table>

Question

How do I make columns of equal width in <table>?

I am dynamically changing the number of columns. Today I have 13 columns. Tomorrow it will be raised to 16. I do not particularly want to recalculate.

Answer 1

I think that this will do the trick:

table{
    table-layout: fixed;
    width: 300px;
}
