Hide header for 1 column

Hide header for 1 column in primeng datatable
I have 3 columns in datatable and I want to hide header for 1 of the columns.
<p-column field="key" header="Name">
<template pTemplate="header">
</template>
</p-column>
The above code snippet shows a very thin line above my first row. I want to get rid of it completely.

I didn't find any thin layer. It works as expected with empty header.
