Print Separatorinset with default values {0, 15, 0, 0}, top, left, bottom, and right distances are 0, 15, 0, 0, i.e. the left side will have a default 15-pixel blank

Use the following code to set the Uitableviewcontroller UITableView split line. Uiedgeinsetszero equivalent to Uiedgeinsetsmake (0, 0, 0, 0).
