gtk:table-set-row-spacing (table row spacing)

table -- a gtk:table widget containing the row whose properties you wish to change
row -- an unsigned integer with the row number whose spacing will be changed
spacing -- an unsigned integer with the number of pixels that the spacing should take up

Changes the space between a given table row and the subsequent row. The gtk:table-set-row-spacing function has been deprecated since version 3.4 and should not be used in newly written code. Use the gtk:widget-margin-top and gtk:widget-margin-bottom functions on the widgets contained in the row if you need this functionality. The gtk:grid widget does not support per-row spacing.
