I think it's a lot easier to make a table with numbers than by hand. I used this today and I thought I'd share it.
Step 1: Select the material you want to type ize.
Step 2: Paste it into text editing. Numbers use the tabs (at least do it for me). Step 3: Use find / replace to replace all tabs with a vertical pipe symbol (|). Copy some of your categories to fill in the search box.
Step 4: Use find / replace to replace all new lines with sequence string symbol – newline pipesymbol. Copy a new line from the text to the search box and replace the field | |, then re-paste newline, and then type | again.
Step 5: Add pipeline to start and end of your file.
Step: Copy the first line and replace all text between dashes You have an empty left top corner that I do, add at least 3 hyphens to the 2nd line between the first set of tubes:
And you're done.
