I am building a custom 3 column table with different different column widths using the block mode. When I enter the table it is not unusual for the columns widths to change depending on the length of content. I wish to lock my widths at 45%, 40% and 15%. I do not want them to resize on their own. Can you please advise the best way to accomplish this? I thought about using Tableberg, but this does not seem compatible with the Post and Page Builder plugin. Please advise when possible. Thank you.
