Answer 2

In professional or academic writing,footnotes are generally used to provide any additional or supplementary information,data,note,reference etc. that cannot be included in the main text for some justifiable reasons.

Explanation:

Now,in any formal or academic writing tables,pictures,charts or graphs are usually used to depict or illustrate any important data or classification relevant to the main topic of writing.In many cases,both numerical and qualitative data are presented in a table format in the middle or end of the main text but somehow some valuable information or reference might not be possible to include in the table.Therefore,a footnote for a table might include additional or supplementary information or notes such as the source of the data presented in the table,any mathematical conversion of the variables mentioned in the table that might be unclear to the reader,any special note to the reader for the clarification or explanation of the table,detailed description of the variables or numbers used in the table which is not possible to include due to space constraint,specific information about the data that requires special attention of the reader pertaining to the table and so on.Hence,footnotes accompanying a table in research or academic writing are common which are mainly used for clarification purposes and providing additional or supplementary information or data pertaining to the table.
