An extended question of this part:
Is there any way to locate the row indices of "Manchester City" and "Manchester United" (observations of the variable "Team" in the table) instead of 'observing the rows directly'?
Or more generally, given a value of a specific variable, how could I get its row index for extraction?

Can you extract the first column (if that corresponds to team names) of data (from the table) and the do a find or strcmp (assuming cell array of strings for the teams) to get the row indices of those matching teams?

Hello Yee,
Geoff's answer is spot on. If you were to put his idea into code, it would look something like this -
index = find(strcmp(table.Team, 'Manchester City') == 1);
To elaborate, table.Team isolates the first column of the table. The function strcmp compares the elements of the column cell vector with the string that you want to match (in this case, ManC). Further, the find function returns the index of the value which was a positive match from the string comparison.
Hope this helps!
