}
public static String [][] to2dim (String source , String outerdelim, String innerdelim) {
String [][] result = new String [source.replaceAll ("[^" + outerdelim + "]", "").length () + 1][];
int count = 0;
for (String line : source.split ("[" + outerdelim + "]"))
{
result [count++] = line.split (innerdelim);
}
return result;
}

This should do for you. [;;]matches only single character ,hence split based on this will add space in between two consecutive ;. So it should be changed to just ;;.
这应该对你有用。[;;]仅匹配单个字符，因此基于此拆分将在两个连续字符之间添加空格;。所以应该改为 just ;;。

You have only one column in 2-nd, 4-th and 6-th rows. Should be 4 columns.
您在第 2、第 4 和第 6 行中只有一列。应该是4列。
