3 different inaccuracies

https://github.com/AppFlowy-IO/AppFlowy-Docs/blob/b058a9f9a63da5b2afa4b78f2bbb7c9401c5b9f4/essential-documentation/contribute-to-appflowy/appflowy-mentorship-program/mentorship-2022/mentee-projects/table.md?plain=1#L11

### Inaccurate ###
"Appflowy"
### Accurate ###
"AppFlowy"
Proper nouns should be capitalized correctly. "AppFlowy" as an official name should be consistently capitalized. I encountered this capitalization issue often in the documentation but as it coincides with other inaccuracies in this sentence I suggested to fix it. The same thing for GitHub which is not always capitalized consistently.

### Inaccurate ###
"aims implementing"
### Accurate ###
"aims `to` implement"
The verb "aims" should be followed by an infinitive ("to implement") rather than a gerund ("implementing").

### Inaccurate ###
"basic tabular content feature"
### Accurate ###
"`a` basic tabular content feature"
Adding the article "a" makes the sentence grammatically complete and more natural.

Open essential-documentation/contribute-to-appflowy/appflowy-mentorship-program/mentorship-2022/mentee-projects/table.md at the linked line 11 and review the sentence containing the three reported inaccuracies. Correct the AppFlowy and GitHub capitalization, change “aims implementing” to “aims to implement,” and add the missing article; done means all three wording issues are fixed in that sentence.
