Table cells, code blocks, panels, etc. lack the ability to specify wrapping behavior

When trying to add content into two columns of a table, I cannot tell the cell to wrap the contents so that the table fits within a window without a horizontal scroll bar at the bottom. This is espcially the case with respect to code blocks.

I have tried placing the content in panels, columns, tables, but I cannot get it to wrap inside a cell or inside of a code block macro.

Even constraining the width of a table or column has not helped. Please let me know if there is a workaround.
