css - markdown adjust the column size and add a break line between rows -

i using

| title | details | |-------|---------| |today sunday| today 2014-01-01| |tmr monday| today 2014-01-02| 

weird thing is, seems first column has fix width. when text length greater width, break text 2 rows.

like in example: show

|today is| |sunday  | 

rather

|today sunday| in same row.

can tell me change width of first column , add border between first row , second row? (add solid line between)

 |today sunday| today 2014-01-01|  |tmr monday| today 2014-01-02| 

if define fixed width column in table, text inside wrap if large fit horizontally.

if want table size largest element of row, remove fixed column width.

in css can't give tr's border properties need set "border-bottom: 1px solid black;" each td element of row.

i suggest post code if want fixing it.
