Table headers not displayed properly by Jekyll-now

I am totally new to markdown/css, and I am trying to set up my blog at Github Pages. I have problems displaying the table headers correctly.

This is how I create them in my .md file, which is coming directly from a notebook generated with Jupyter and R:

<table>
<thead><tr><th></th><th scope=col>ID</th><th scope=col>City</th><th scope=col>Province</th><th scope=col>Italians</th><th scope=col>Population</th><th scope=col>Percentage</th><th scope=col>Lat</th><th scope=col>Lon</th></tr></thead>
<tbody>

and this is how they are displayed on my blog page, so I cannot read the headers:
<th scope=col>ID</th><th scope=col>City</th><th scope=col>Province</th><th scope=col>Italians</th><th scope=col>Population</th><th scope=col>Percentage</th><th scope=col>Lat</th><th scope=col>Lon</th><th scope=row>14</th><th scope=row>5</th><th scope=row>2</th><th scope=row>1</th><th scope=row>11</th><th scope=row>7</th><th scope=row>3</th><th scope=row>15</th><th scope=row>12</th><th scope=row>17</th><th scope=row>16</th><th scope=row>6</th><th scope=row>13</th>

What am I doing wrong here? Thanks.
