I am not sure what is the problem with Outlook 2013, but you can try to achieve same layout with div structure
HTML:
text in the table cell.
and another line of text.
and a third line.
Hello. This is sample text. This is another sentence. Hello. This is sample text. This is another sentence. Hello. This is sample text. This is another sentence.
CSS:
.outer {
width : 50%;
height : 50%;
background-color: green;
}
.first {
background-color: red;
float : left;
}
.second {
background-color: yellow;
}
