Description:
The implementation height (line spacing) is essentially through the upper spacing, It is controlled by the bottom spacing, not the height of the text (the distance from the top edge to the bottom edge of the text). If the pixels of the text are 16px, the larger the line height is, the pixels of the text will remain unchanged, but the upper and lower spacing of the text will change. If the line height is 26px, then the top and bottom spacing are 5px each. That is, increasing the row height will only increase the top and bottom spacing.
Tips: The line height of multi-line text is actually from the bottom edge of the line of text to the bottom edge of the next line of text
