Build the table for log-rank test calculation.

1 | ```
logrank.table(survival, delta, trt)
``` |

`survival` |
Time to event or censoring. |

`delta` |
Event indicator: 1 for observed cases, 0 for censored cases. |

`trt` |
Treatment assignment indicator: 1 for treatment group, 0 for control group. |

Build a table for log-rank test which ouputs *ordered* `survival`

as follow-up times, `delta`

as event indicators,`trt`

as treatment assignement (treated=1, control=0), `Y`

as the at-risk numbers, `P1`

as the proportion of treated set, `P0`

as the proportion of the control set.

In addition, the output also include `O1`

as the observed events from the treatment arm, `E1`

as the expected events from the treatment arm, `Cov`

as the estimated variance.
