VBA通过用户选择其大小来调整数组大小

I am trying to make a string array of keywords. The string array will have a set number of columns (various number of keywords for 3 different fruits: apple, banana, orange). However, the column for each row will be a different size based on how many keywords the user is looking for, for EACH fruit. The user may be looking for 1 keyword for apple, 2 keywords for banana, and 3 keywords for orange. when it's all said and done, I want a string array of 3xC, where C is the largest number of keywords, and the unfilled cells are empty. Here is the code I have so far, but I am unsure of how to dimensionalize the array. I am trying to make a string array of keywords.
