cannot enter data into table cells in word 2016

[jalea148]

am using sticky keys and have tried cut and paste and direct typing . when I try to enter in this particular cell it wants to put the data in the first cell of the next row . the table created earlier and when I reopened it the column formatting had changed and I reformat it . I have not tried saving and restarting the computer . data entry such as cut and pasting, typing seems to be working in other applications .
