Column with getting narrow in mobile

Hi Tobias. Thank for the great plugin. Recently I am having trouble with column width from mobile device.In the first row I have used html code to show image. In the page I have used the following code to show full width from Desktop:
.tablepress-id-5 {
max-width: 100% !important;
min-width: 100px !important;
}
With this the table can be viewed well organised from desktop. But from mobile phone I am unable to solve the problem yet. The columns are getting squeezed and very narrow so that the image (from html code) inside is not at all visible. I am a beginner in html coding. please help.
