You can use awk like this :
awk 'BEGIN {
x = 0;
print "<table border="1">"
}
{
if (NF == 1){
print "<tr ><td colspan="2">"$i"</td>";
print "</tr>"
} else {
if (x == 0){
x++;
print "<tr><td>"$i"</td>"
} else {
x = 0;
print "<td>"$i"</td></tr>"
}
}
}
END {
print "</table>"
}' input.txt > table.html
Feel free to add any additional style
For older version of awk, you can use the following, tested on an awk implementation of 2009-11-26 (from one-true-awk) :
awk 'BEGIN {
x = 0;
y = 0;
print "<table border="1">"
}
{
for (i = 1; i<=NF ; i++){
if (NF == 1){
print "<tr ><td colspan="2">"$i"</td></tr>";
} else {
if (x == 0 && y == 0){
print "<tr><td>"$i" ";
x++;
}
else if (x == 0 && y == 1){
print "<td>"$i" ";
x++;
}
else if (x==(NF-1)){
x = 0;
y++;
if (y == 2){
y = 0;
print ""$i"</td></tr>";
}
else{
print ""$i"</td>";
}
}
else {
print ""$i" ";
x++;
}
}
}
}
END {
print "</table>"
}' input.txt > table.html
For this last version, x is incremented at each space delimiter until we reach NF-1 which is the last word and we should put an ending </td>. The decision for the ending </tr> depends on the value of y which is incremented at each line and re-initialized when the max count of <td> is reached (here 2 <td> per <tr>)
