How to get a fixed picture in the field without affect by responsive effect?
Tables are by definition "responsive" (quotes intended), meaning they will give more space to the more "filled" cell. You need to tell the browser to reserve a certain amount of space for the cell with the following css:

.views-field-uc-product-image {
  min-width: 110px;
  max-width: 110px;
}


The extra 10 pixels are to account for the padding around the image. The max-width: 110px is added to ensure the cell will also not take more space then needed.
